FUJITSU SEMICONDUCTOR DATA SHEET DS07-12545-1E 8-bit Proprietary Microcontroller CMOS F2MC-8L MB89960 Series MB89965/P965A/F969A/ MB89PV960 s DESCRIPTION The MB89960 series is a single-chip microcontroller that utilizes the F2MC-8L core for low voltage and high speed performance. The microcontroller contains a range of peripheral functions including timers, a serial interface, I2C interface, A/D converter, and external interrupts. The internal I2C interface plies with the SM bus standard and supports an SM bus battery controller. s Features - Range of package options - QFP and MQFP packages (0.8 mm pitch) - LQFP package (0.5 mm and 0.65 mm pitch) - High speed operation at low voltage Minimum instruction execution time = 0.4 µs (for a 10 MHz oscillation) - F2MC-8L CPU core Instruction set optimized for controller applications - Multiplication and division instructions - 16-bit arithmetic operations - Bit test branch instructions - Bit manipulation instructions, etc. - Dual-clock control system - Main clock : 10 MHz max. (Four speed settings available, oscillation halts in sub-clock mode) - Sub-clock : 32.768 k Hz (Operation clock for sub-clock mode) - - - - Four channels 8/16-bit timer/counter (8-bit × 2 channels or 16-bit × 1 channel) 21-bit timebase timer Clock prescaler (15-bit) - Serial I/O Selectable transfer format (MSB-first or LSB-first) supports munications with a wide range of devices. - A/D converter 10-bit × 4 channels MB89960 Series - External interrupts - External interrupt 1 (3 channels) Three independent interrupt inputs can be used to recover from low-power consumption modes (with edgedetection function) - External interrupt 2 (1 channel with 8 inputs) Eight inputs can be used to recover from low-power consumption modes (with “L” level detection function) - - - - Low-power consumption modes (standby modes) Stop mode (As all oscillations halt in sub-clock mode, current consumption falls to almost zero.) Sleep mode (The CPU stops to reduce...
