The MB90910 series, loaded 1 channel FULL-CAN controller and Flash ROM, is general-purpose Cypress 16-bit microcontroller
designing for automotive and industrial applications. Its main feature is the on-board CAN controllers, which conform to Ver 2.0 Part
A and Part B, while supporting a very flexible message buffer scheme and so offering more functions than a normal FULL-CAN
approach. With the new 0.18
m CMOS technology, Cypress now offers on-chip Flash ROM program memory up to 128 Kbytes.
The power supply (1.8 V) is supplied to the MCU core from an internal regulator circuit. This creates a major advantage in terms of
EMI and power consumption.
The internal PLL clock frequency multiplier provides an internal 31.25 ns instruction execution time from an external 4 MHz clock.
The unit features a 4-channel input capture unit 1 channel 16-bit free-run timer, 2-channel LIN-UART,
1-channel UART, and 16-channel 8/10-bit A/D converter as the peripheral resource.
