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.

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 channelsMB89960 Series

? External interrupts

? External interrupt 1 (3 channels)

Three independent interrupt inputs can be used to recover from low-power consumption modes (with edge-detection 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 the current consumption to approximately 1/3 of normal.)

? Clock mode (All operation halts other than the clock prescaler resulting in very low power consumption.)

? I2C interface*

? Supports Intel SM bus and Philips I2C bus standards.

? Uses a two-wire data transfer protocol.

? Max. 35 I/O ports

? Output-only ports (N-ch open drain) : 6

? General-purpose I/O ports (CMOS) : 21

? Output-only ports (CMOS) : 8
