MB8999x

FUJITSU SEMICONDUCTOR DATA SHEET DS07-12538-1E 8-bit Proprietary Microcontroller CMOS F2MC-8L MB89990 Series MB89997 s 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. *: F2MC stands for FUJITSU Flexible Microcontroller. s 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 (Continued) s PACKAGE 28-pin Plastic SOP 28-pin Plastic SH-DIP 48-pin Ceramic MQFP (FPT-28P-M17) (DIP-28P-M03) (MQP-48C-P01) MB89990 Series (Continued) 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.)
