The TS80C52X2 retains all features of the 80C51 with extended ROM/EPROM capacity (8 Kbytes), 256 bytes of internal RAM, a 6-source, 4-level interrupt system, an on-chip oscilator and three timer/counters. In addition, the TS80C52X2 has a dual data pointer, a more versatile serial channel that facilitates multiprocessor communication (EUART) and an X2 speed improve- ment mechanism. The fully static design of the TS80C52X2 allows to reduce system power consumption by bringing the clock frequency down to any value, even DC, without loss of data. The TS80C52X2 has 2 software-selectable modes of reduced activity for further reduction in power consumption. In the idle mode the CPU is frozen while the timers, the serial port and the interrupt system are still operating. In the power-down mode the RAM is saved and all other functions are inoperative.

Port 0 pins that have 1s written to them float and can be used as high impedance inputs.Port 0 pins must be polarized to Vcc or Vss in order to prevent any parasitic current consumption. Port 0 is also the multiplexed low-order address and data bus during access to external program and data memory. In this application, it uses strong internal pull-up when emitting 1s. Port 0 also inputs the code bytes during EPROM programming. External pull-ups are required during program verification during which P0 outputs the code bytes. P1.0-P1.7 1-8 2-9 40-44 1-3 I/O Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups. Port 1 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 1 pins that are externally pulled low will source current because of the internal pull-ups. Port 1 also receives the low-order address byte during memory programming and verification. Alternate functions for Port 1 include: 1 2 40 I/O T2 (P1.0): Timer/Counter 2 external count input/Clockout 2 3 41 I T2EX (P1.1): Timer/Counter 2 Reload/Capture/Direction Control P2.0-P2.7 21- 28 24- 31 18-25 I/O Port 2: Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. Port 2 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 2 pins that are externally pulled low will source current because of the internal pull-ups. Port 2 emits the high- order address byte during fetches from external program memory and during accesses to external data memory that use 16-bit addresses (MOVX atDPTR).In this application, it uses strong internal pull-ups emitting 1s. During accesses to external data memory that use 8-bit addresses (MOVX atRi), port 2 emits the contents of the P2 SFR. Some Port 2 pins receive the high order address bits during EPROM programming and verification: P2.0 to P2.4 P3.0-P3.7 10- 17 11, 13- 19 5, 7-13 I/O Port 3: Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, Port 3 pins that are externally pulled low will source current because of the internal pull-ups. Port 3 also serves the special features of the 80C51 family, as listed below. 10 11 5 I RXD (P3.0): Serial input port 11 13 7 O TXD (P3.1): Serial output port 12 14 8 I INT0 (P3.2): External interrupt 06 TS8xCx2X2 4184G–8051–09/06

An internal diffused resistor to VSS permits a power-on reset using only an external capacitor to VCC. ALE/PROG 30 33 27 O (I) Address Latch Enable/Program Pulse: Output pulse for latching the low byte of the address during an access to external memory. In normal operation, ALE is emitted at a constant rate of 1/6 (1/3 in X2 mode) the oscillator frequency, and can be used for external timing or clocking. Note that one ALE pulse is skipped during each access to external data memory. This pin is also the program pulse input (PROG) during EPROM programming. ALE can be disabled by setting SFR’s AUXR.0 bit. With this bit set, ALE will be inactive during internal fetches. PSEN 29 32 26 O Program Store ENable: The read strobe to external program memory. When executing code from the external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory. PSEN is not activated during fetches from internal program memory. EA/VPP 31 35 29 I External Access Enable/Programming Supply Voltage: EA must be externally held low to enable the device to fetch code from external program memory locations 0000H and 3FFFH (RB) or 7FFFH (RC), or FFFFH (RD). If EA is held high, the device executes from internal program memory unless the program counter contains an address greater than 3FFFH (RB) or 7FFFH (RC) EA must be held low for ROMless devices. This pin also receives the 12.75V programming supply voltage (VPP) during EPROM programming. If security level 1 is programmed, EA will be internally latched on Reset.

TS80C52X2 Enhanced Features In comparison to the original 80C52, the TS80C52X2 implements some new features, which are: • The X2 option • The Dual Data Pointer • The 4 level interrupt priority system • The power-off flag • The ONCE mode • The ALE disabling • Some enhanced features are also located in the UART and the Timer 2 X2 Feature The TS80C52X2 core needs only 6 clock periods per machine cycle. This feature called ”X2” provides the following advantages: • Divide frequency crystals by 2 (cheaper crystals) while keeping same CPU power • Save power consumption while keeping same CPU power (oscillator power saving) • Save power consumption by dividing dynamically operating frequency by 2 in operating and idle modes • Increase CPU power by 2 while keeping same crystal frequency In order to keep the original C51 compatibility, a divider by 2 is inserted between the XTAL1 signal and the main clock input of the core (phase generator). This divider may be disabled by software. Description The clock for the whole circuit and peripheral is first divided by two before being used by the CPU core and peripherals. This allows any cyclic ratio to be accepted on XTAL1 input. In X2 mode, as this divider is bypassed, the signals on XTAL1 must have a cyclic ratio between 40 to 60%. Figure 1. shows the clock generation block diagram. X2 bit is validated on XTAL1÷2 rising edge to avoid glitches when switching from X2 to STD mode. Figure 2 shows the mode switching waveforms.

TS8xCx2X2Figure 2. Mode Switching Waveforms The X2 bit in the CKCON register (See Table 3.) allows to switch from 12 clock cycles per instruction to 6 clock cycles and vice versa. At reset, the standard speed is activated (STD mode). Setting this bit activates the X2 feature (X2 mode). Note: In order to prevent any incorrect operation while operating in X2 mode, user must be aware that all peripherals using clock frequency as time reference (UART, timers) will have their time reference divided by two. For example a free running timer generating an interrupt every 20 ms will then generate an interrupt every 10 ms. UART with 4800 baud rate will have 9600 baud rate. Table 3.
