FUJITSU SEMICONDUCTOR DATA SHEET DS07-12518-8E 8-bit Proprietary Microcontroller CMOS F2MC-8L MB89170/170A/170L Series MB89173/P173/174A/P175A/PV170A MB89173L/174L s DESCRIPTION The MB89170/170A/170L series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit, single-chip microcontrollers. In addition to a compact instruction set, the microcontrollers contain a great variety of peripheral functions such as timers, a serial interface, a DTMF generator, and external interrupts, making it suitable for circuit control such as required in telephones. *: F2MC stands for FUJITSU Flexible Microcontroller. s FEATURES F2MC-8L family CPU core Maximum memory space: 64 Kbytes Minimum execution time/interrupt processing time MB89170 series: 1.1 µs/10 µs (at 3.58 MHz oscillation) MB89170A/170L series: 0.6 µs/5.4 µs (at 7.16 MHz oscillation) Dual-clock control system (MB89170/170A series only) I/O ports: max. 37 ports 21-bit timebase counter Watch prescaler (MB89170/170A series only) Watchdog timer 8/16-bit timer/counter: 1 channel (Continued) s PACKAGE 48-pin Plastic QFP 48-pin Ceramic MQFP (FPT-48P-M16) (MQP-48C-P01) MB89170/170A/170L Series (Continued) 8-bit serial I/O: 1 channel DTMF generator (MB89170/170A series only) Selectable oscillation frequency (MB89170A series only) External interrupt 1: 3 channels Three channels are independent and capable of using for wake-up from low-power consumption modes (wi...
