to-fall, H width measurement and rise-to-rise)

16-bit timer/

counter

16-bit timer operation (operating clock period : 1 tinst*3, external)

16-bit event counter operation (select rising, falling, or both edges)

16-bit × 1 ch

Serial I/O

8 bit length, Selection of LSB first or MSB first, Transfer clock (2, 8, 32 tinst*3, external)

UART/SIO

CLK synchronous/CLK asynchronous data transfer capability (8, 9 bit with parity bit, or 7,8

bit without parity bit) .

Built-in baud rate generator provides selection of 14 baud rate settings.

UART

CLK synchronous/CLK asynchronous data transfer capability (4, 6, 7, 8 bit with parity bit,

or 5, 7, 8, 9 bit without parity bit) .

Built-in baud rate generator provides selection of 14 baud rate settings.

External clock output, 2-channel 8-bit PWM timer output also available for baud rate set-

tings.

External

interrupt 1

Single-clock : 4-channel independent, dual-clock : 3-channel independent

Selection of rising, falling, or both edge detection.

Can be used for recovery from standby mode (edge detection also available in stop mode) .

External

interrupt 2

Except for MB89F538L : 8-channel independent L level detection, MB89F538L : 7-channel

independent L level detection

Can be used for recovery from standby mode.

6-bit PPG,

12-bit PPG

Can generate square wave signals with programmable period.

6-bit × 1 channel or 12-bit × 2 channels.

1-channel , compatible with Intel System Administrator bus version 1.0 and Philips I2C

I2C bus interface specifications.

2-line communications (on MB89PV530/P538/F538L/537C/538C)

A/D converter

10-bit resolution × 8 channels.

A/D conversion functions (conversion time : 60 tinst *3)

Supports repeated calls from external clock (except for MB89F538L)

Supports repeated calls from internal clock.

Standard voltage input provided (AVR)

Standby modes

(power saving

modes)

Sleep mode, stop mode, sub clock mode, watch mode.

Process

CMOS

*1 : Depends on operating frequency.

*2 : Using external ROM and MBM27C512.

*3 : tinst represents instruction execution time. This can be selected as 1/4, 1/8, 1/16, 1/64 of the main clock

cycle or 1/2 of the sub clock cycle.

Note : MB89537/538 have no built-in I2C functions.

To use I2C functions, choose the MB89PV530/P538/F538L/MB89537C/538C.
