■ DESCRIPTIONS

The FUJITSU MB90420G/5G (A) Series is a 16-bit general purpose high-capacity microcontroller designed for vehicle meter control applications etc.

The instruction set retains the same AT architecture as the FUJITSU original F2MC-8L and F2MC-16L series, with further refinements including high-level language instructions, expanded addressing mode, enhanced (signed) multipler-divider computation and bit processing.

In addition, A 32-bit accumulator is built in to enable long word processing.

■ FEATURES

• 16-bit input capture (4 channels)

Detects rising, falling, or both edges.

16-bit capture register × 4

Pin input edge detection latches the 16-bit free-run timer counter value, and generates an interrupt request.

• 16-bit reload timer (2 channels)

16-bit reload timer operation (select toggle output or one-shot output)

Event count function selection provided

• Clock timer (main clock)

Operates directly from oscillator clock.

Compensates for oscillator deviation

Read/write enabled second/minute/hour register Signal interrupt

• 16-bit PPG (3 channels)

Output pins (3) , external trigger input pin (1)

Output clock frequencies : fCP, fCP/22, fCP/24, fCP/26

• Delay interrupt

Generates interrupt for task switching.

Interruptions to CPU can be generated/deleted by software setting.

• External interrupts (8 channels)

8-channel independent operation

Interrupt source setting available : “L” to “H” edge/ “H” to “L” edge/ “L” level/ “H” level.

• A/D converter

10-bit or 8-bit resolution × 8 channels (input multiplexed)

Conversion time : 6.13 µs or less (at fCP = 16 MHz)

External trigger startup available (P50/INT0/ADTG)

Internal timer startup available (16-bit reload timer 1)

• UART (2 channels)

Full duplex double buffer type

Supports asynchronous/synchronous transfer (with start/stop bits)

Internal timer can be selected as clock (16-bit reload timer 0)

Asynchronous : 4808 bps, 5208 bps, 9615 bps, 10417 bps, 19230 bps, 38460 bps, 62500 bps, 500000 bps

Synchronous : 500 Kbps, 1Mbps, 2Mbps (at fCP = 16 MHz)

• CAN interface *1

Conforms to CAN specifications version 2.0 Part A and B.

Automatic resend in case of error.

Automatic transfer in response to remote frame.

16 prioritized message buffers for data and messages for data and ID

Multiple message support

Receiving filter has flexible configuration : All bit compare/all bit mask/two partial bit masks

Supports up to 1 Mbps CAN WAKEUP function (connects RX internally to INT0)

• LCD controller/driver (1 channel)

Segment driver and command driver with direct LCD panel (display) drive capability

• Low voltage/Program Looping detect reset *2

Automatic reset when low voltage is detected

Program Looping detection function

• Stepping motor controller (4 channels)

High current output for all channels × 4

Synchronized 8/10-bit PWM for all channels × 2

• Sound generator

8-bit PWM signal mixed with tone frequency from 8-bit reload counter.

PWM frequencies : 62.5 kHz, 31.2 kHz, 15.6 kHz, 7.8 kHz (at fCP = 16MHz)

Tone frequencies : 1/2 PWM frequency, divided by (reload frequency +1)
