MB89965 General 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, I2Cinterface, A/D converter, and external interrupts. The internal I 2C interface complies with the SM bus standard and supports an SM bus battery controller.
MB89965 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
• 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
