■ OUTLINE

The MB89990 series microcontrollers contain various resources such as timers, external interrupts, and remotecontrol functions, as well as an F2MC*-8L CPU core for low-voltage and high-speed operations. These singlechip microcontrollers are suitable for small devices such as remote controllers incorporating 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

• External interrupts

Edge detection (Edge selection enabled): 3 channels

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

• Internal remote-control transmission frequency generator

• Low-power consumption modes

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

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

• Packages

SOP-28 and SH-DIP-28
