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 complies 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 kHz (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 communications with a wide range of devices.
A/D converter
10-bit × 4 channels
