80C652/83C652CMOS single-chip 8-bit microcontrollers

1996 Aug 15

DESCRIPTION

The P80C652/83C652 Single-Chip 8-Bit

Microcontroller is manufactured in an

advanced CMOS process and is a derivative

of the 80C51 microcontroller family. The

80C652/83C652 has the same instruction set

as the 80C51. Three versions of the

derivative exist:

83C652 — 8k bytes mask programmable

ROM

80C652 — ROMless version

87C652 — EPROM version (described in a

separate chapter)

This device provides architectural

enhancements that make it applicable in a

variety of applications for general control

systems. The 8XC652 contains a non-volatile

8k × 8 read-only program memory, a volatile

256 × 8 read/write data memory, four 8-bit I/O

ports, two 16-bit timer/event counters

(identical to the timers of the 80C51), a

multi-source, two-priority-level, nested

interrupt structure, an I

C interface, UART

and on-chip oscillator and timing circuits. For

systems that require extra capability, the

8XC652 can be expanded using standard

TTL compatible memories and logic.

The device also functions as an arithmetic

processor having facilities for both binary and

BCD arithmetic plus bit-handling capabilities.

The instruction set consists of over 100

instructions: 49 one-byte, 45 two-byte and 17

three-byte. With a 16(24)MHz crystal, 58% of

the instructions are executed in 0.75(0.5)µs

and 40% in 1.5(1)µs. Multiply and divide

instructions require 3(2)µs.

I Ground: 0V reference. With the QFP package all V

pins (V

SS1

to V

SS4

) must be

connected.

40 44 38 I Power Supply: This is the power supply voltage for normal, idle, and power-down

operation.

P0.0–0.7 39–32 43–36 37–30 I/O Port 0: Port 0 is an open-drain, bidirectional I/O port. Port 0 pins that have 1s written to

them float and 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 pull-ups when emitting 1s.

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, except P1.6 and P1.7

which are open drain. 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. (See DC Electrical Characteristics:

). Alternate functions include:

P1.6 7 8 2 I/O SCL: I

C-bus serial port clock line.

P1.7 8 9 3 I/O SDA: I

C-bus serial port data line.

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 being pulled low will source current because of the

internal pull-ups. (See DC Electrical Characteristics: I

). 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 pull-ups when emitting 1s. During accesses to external data memory

that use 8-bit addresses (MOV @Ri), port 2 emits the contents of the P2 special function

P3.0–P3.7 10–17 11,

13–19

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 being pulled low will source current because of the

pull-ups. (See DC Electrical Characteristics: I

). 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

13 15 9 I INT1 (P3.3): External interrupt

14 16 10 I T0 (P3.4): Timer 0 external input

15 17 11 I T1 (P3.5): Timer 1 external input

16 18 12 O WR (P3.6): External data memory write strobe

17 19 13 O RD (P3.7): External data memory read strobe

RST 9 10 4 I Reset: A high on this pin for two machine cycles while the oscillator is running, resets the

device. An internal diffused resistor to V

permits a power-on reset using only an external

capacitor to V

ALE 30 33 27 I/O Address Latch Enable: 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

the oscillator frequency. Note that one ALE pulse is skipped during each access to external

data memory.

PSEN 29 32 26 O Program Store Enable: Read strobe to external program memory via Port 0 and Port 2. It

is activated twice each machine cycle during fetches from the external program memory.

When executing out of external program memory two activations of PSEN

are skipped

during each access to external data memory. PSEN

is not activated (remains HIGH) during

no fetches from external program memory. PSEN

can sink/source 8 LSTTL inputs and can

drive CMOS inputs without external pull–ups.

EA 31 35 29 I External Access: If during a RESET, EA is held at TTL, level HIGH, the CPU executes out

of the internal program memory ROM provided the Program Counter is less than 8192. If

during a RESET, EA

is held a TTL LOW level, the CPU executes out of external program

memory. EA

is not allowed to float.

XTAL1 19 21 15 I Crystal 1: Input to the inverting oscillator amplifier and input to the internal clock generator

circuits.

XTAL2 18 20 14 O Crystal 2: Output from the inverting oscillator amplifier.

NOTE:

To avoid “latch-up” effect at power-on, the voltage on any pin at any time must not be higher than V

+ 0.5V or V

– 0.5V, respectively.
