M30291FCHP

Product Overview

The M30291FCHP is a 16-bit microcontroller from Renesas Electronics' M16C/29 family. It is based on the M16C/60 CPU core and operates at a maximum frequency of 20 MHz.

The device integrates 128 KB of Flash memory, 12 KB of RAM, 4 KB of data Flash, 16 channels of 10-bit ADC, eight 16-bit timer channels, and CAN, I²C, IEBus, SIO, and UART/USART communication interfaces. The standard M30291FCHP#U3A variant is supplied in a 64-pin LFQFP package measuring 10 mm × 10 mm.

The M16C/29 family is intended for embedded control applications where a compact 16-bit MCU with integrated Flash, analog conversion, timers, communication interfaces, and 2.7 V–5.5 V operation is required.

Ordering-code note: Renesas lists M30291FCHP#U3A, #U5A and #U7A as specific ordering variants. Since the supplied model is M30291FCHP without a suffix, the specifications below use the common M30291FCHP base device and the Renesas-listed 64-LFQFP configuration.
