Cypress Semiconductor 

MB90340E Series

F2MC-16LX 16-bit Microcontroller

Datasheet

The MB90340E series with up to 2 FULL-CAN interfaces is especially designed for automotive and other industrial applications. Its

main feature are the on-board CAN Interfaces, which conform to V2.0 Part A and Part B, while supporting a very flexible message

buffer scheme and so offering more functions than a normal full CAN approach.

The power to the MCU core (3 V) is supplied by a built-in regulator circuit, giving these microcontrollers superior performance in

terms of power consumption and tolerance to EMI.

Features

CPU

 Instruction system best suited to controller

- Wide choice of data types (bit, byte, word, and long word)

- Wide choice of addressing modes (23 types)

- Enhanced functionality with signed multiply and divide

instructions and the RETI instruction

- Enhanced high-precision computing with 32-bit accumulator

 Instruction system compatible with high-level language (C

language) and multitask

- Employing system stack pointer

- Various enhanced pointer indirect instructions

- Barrel shift instructions

 Increased processing speed

- 4-byte instruction queue

Serial interface

 LIN-UART : 4 channels

- Equipped with full-duplex double buffer

- Clock-asynchronous or clock-synchronous serial transmission

is available

 I2C interface : 2 channels (only for devices with a C suffix in

the part number)

- Up to 400 kbps transfer rate

Interrupt controller

 Powerful 8-level, 34-condition interrupt feature

 Up to 16 external interrupts are supported

 Automatic data transfer function independent of CPU

- Expanded intelligent I/O service function (EI2OS) : up to 16

channels

I/O ports

 General-purpose input/output port (CMOS output)

- 80 ports (for devices without an S suffix in the part number -

i.e. devices that support the sub clock)

- 82 ports (for devices with an S suffix in the part number - i.e.

devices that do not support the sub clock)

8/10-bit A/D converter

 16 channels (only for devices without a C suffix in the part

number)

 24 channels (only for devices with a C suffix in the part

number)

 Resolution is selectable between 8-bit and 10-bit.

 Activation by external trigger input is allowed.

 Conversion time : 3 s (at 24 MHz machine clock, including

sampling time)

Address match detection (program patch) func-

tion

 Detects address matches against 6 address pointers

Timer

 Time-base timer, watch timer, watchdog timer : 1 channel

 8/16-bit PPG timer : 8-bit  16 channels, or 16-bit  8

channels

 16-bit reload timer : 4 channels

 16-bit input/output timer

- 16-bit free-run timer : 2 channels

(FRT0 : ICU 0/1/2/3, OCU 0/1/2/3, FRT1 : ICU 4/5/6/7, OCU 4/

5/6/7)

- 16-bit input capture: (ICU): 8 channels

- 16-bit output compare: (OCU): 8 channels

 16 built-in message buffers

 CAN wake-up function

Low power consumption (standby) mode

 Sleep mode (a mode that halts CPU operating clock)

 Timebase timer mode (a mode where only the oscillation

clock, sub clock, timebase timer and watch timer operate)

 Watch mode (a mode that operates sub clock and watch

timer only)

 Stop mode (a mode that stops oscillation clock and sub

clock)

 CPU intermittent operation mode

Clock modulation circuit
