MB89191集成电路（IC）的微控制器规格书PDF中文资料

■ OUTLINE

The MB89190/190A series microcontrollers contain various resources such as timers, serial interfaces, A/D converters, external interrupts, and remote-control functions, as well as an F2MC*-8L CPU core for low-voltage and high-speed operations. These single-chip microcontrollers are suitable for small devices such as remote controllers with compact packages.

■ FEATURES

• Minimum execution time: 0.95 µs at 4.2 MHz (VCC= 2.7 V)

• F2MC-8L family CPU core

• Two timers

8/16-bit timer/counter

20-bit timebase counter

• Serial interface

8-bit synchronous serial (Selectable transfer direction allows communication with various equipment.)

• External interrupts

Edge detection (Selectable edge): 3 channels

Low-level interrupt (Wake-up function): 8 channels

• A/D converter (MB89190A series only)

8-bit successive approximation type: 8 channels

• Built-in remote-control transmitting frequency generator

• Low-power consumption modes

Stop mode (Almost no current consumption occurs because oscillation stops.)

Sleep mode (The current consumption is reduced about 1/3 of that during normal operation because the CPU stops.)

•Packages

SOP-28, SH-DIP-28, and DIP-28
