TEMIC’s TSC87C51 is high performance CMOS

EPROM version of the 80C51 CMOS single chip 8 bit

microcontroller.

The fully static design of the TSC87C51 allows to

reduce system power consumption by bringing the clock

frequency down to any value, even DC, without loss of

data.

The TSC87C51 retains all the features of the 80C51 with

some enhancement: 4 K bytes of internal code memory

(EPROM); 128 bytes of internal data memory (RAM);

32 I/O lines; two 16 bit timers; a 5-source, 2-level

interrupt structure; a full duplex serial port with framing

error detection; a power off flag; and an on-chip

oscillator.

The TSC87C51 has 2 software-selectable modes of

reduced activity for further reduction in power

consumption. In the idle mode the CPU is frozen while

the RAM, the timers, the serial port and the interrupt

system continue to function. In the power down mode

the RAM is saved and all other functions are inoperative.

The TSC87C51 is manufactured using non volatile

SCMOS process which allows it to run up to:

25 MHz with VCC = 5 V

10%.

VSS1

Secondary ground (not on DIP). Provided to reduce ground bounce and improve power supply by–passing.

Note: This pin is not a substitute for the VSS pin. Connection is not necessary for proper operation.

VCC

Supply voltage during normal, Idle, and Power Down operation.

Port 0

Port 0 is an 8 bit open drain bi-directional I/O port. Port 0 pins that have 1’s written to them float, and in that state can

be used as high-impedance inputs.

Port 0 is also the multiplexed low-order address and data bus during accesses to external Program and Data Memory.

In this application it uses strong internal pullups when emitting 1’s.

Port 0 can sink eight LS TTL inputs.

Port 0 is used as data bus during EPROM programming and program verification.

Port 1

Port 1 is an 8 bit bi-directional I/O port with internal pullups. Port 1 pins that have 1’s written to them are pulled high

by the internal pullups, and in that state can be used as inputs. As inputs, Port 1 pins that are externally being pulled

low will source current (IIL, in the DC parameters section) because of the internal pullups.

Port 1 can sink/ source three LS TTL inputs. It can drive CMOS inputs without external pullups.

Port 1 receives the low–order address byte during EPROM programming and program verification.

Port 2

Port 2 is an 8 bit bi-directional I/O port with internal pullups. Port 2 pins that have 1’s written to them are pulled high

by the internal pullups, and in that state can be used as inputs. As inputs, Port 2 pins that are externally being pulled

low will source current (IIL, in the DC parameters section) because of the internal pullups.

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 @DPTR). In this application, it uses strong internal pullups when

emitting 1’s. During accesses to external Data Memory that use 8 bit addresses (MOVX @Ri), Port 2 emits the contents

of the P2 Special Function Register.

Port 2 can sink/source three LS TTL inputs. It can drive CMOS inputs without external pullups.

Some Port 2 pins receive the high–order address bits and control signals during EPROM programming and program

verification.

Port 3

Port 3 is an 8 bit bi-directional I/O port with internal pullups. Port 3 pins that have 1’s written to them are pulled high

by the internal pullups, and in that state can be used as inputs. As inputs, Port 3 pins that are externally being pulled

low will source current (IIL, in the DC parameters section) because of the pullups.

P3.5

P3.6

P3.7

T1 (Timer 1 external input)

WR (external Data Memory write strobe)

RD (external Data Memory read strobe)

Port 3 can sink/source three LS TTL inputs. It can drive CMOS inputs without external pullups.

Some Port 3 pins receive control signals during EPROM programming and program verification.

RST

A high level on this pin for two machine cycles while the oscillator is running resets the device. An internal pull-down

resistor permits Power-On reset using only a capacitor connected to V

. The port pins will be driven to their reset

condition when a minimum VIH1 voltage is applied whether the oscillator is started or not (asynchronous reset).

ALE/PROG

Address Latch Enable output for latching the low byte of the address during accesses to external memory. ALE is

activated as though for this purpose at a constant rate of 1/6 the oscillator frequency except during an external data

memory access at which time one ALE pulse is skipped.

ALE can sink/source 8 LS TTL inputs. It can drive CMOS inputs without external pullup.

If desired, to reduce EMI, ALE operation can be disabled by setting bit 0 of SFR location 8Eh (MSCON). With this

bit set, the pin is weakly pulled high. However, ALE remains active during MOVX, MOVC instructions and external

fetches. Setting the ALE disable bit has no effect if the microcontroller is in external execution mode (EA=0).

Throughout the remainder of this datasheet, ALE will refer to the signal coming out of the ALE/PROG pin, and the

pin will be referred to as the ALE/PROG pin.

PSEN

Program Store Enable output is the read strobe to external Program Memory. PSEN is activated twice each machine

cycle during fetches from external Program Memory. (However, when executing out of external Program Memory, two

activations of PSEN are skipped during each access to external Data Memory). PSEN is not activated during fetches

from internal Program Memory. PSEN can sink/source 8 LS TTL inputs. It can drive CMOS inputs without an external

pullup.

EA/VPP

External Access enable. EA must be strapped to VSS in order to enable the device to fetch code from external Program

Memory locations 0000h to FFFFh. Note however, that if any of the Security bits are programmed, EA will be internally

latched on reset.

EA should be strapped to VCC for internal program execution.

This pin also receives the programming supply voltage (VPP) during EPROM programming.

XTAL1

Input to the inverting amplifier that forms the oscillator. Receives the external oscillator signal when an external

oscillator is used.

XTAL2

Output from the inverting amplifier that forms the oscillator. This pin should be floated when an external oscillator

is used.
