Product details
Overview
M30291FAVHP#UTQ from Renesas Electronics is a 16-bit CMOS microcontroller in the M16C/29 Group, designed for embedded control applications requiring integrated peripherals, low-power operation, and industrial-grade reliability. It features 256 KB on-chip flash memory, 16 KB RAM, a 16-bit CPU core operating at up to 20 MHz, and supports CAN 2.0B protocol via dedicated controller. It is commonly deployed in motor control subsystems of HVAC equipment and industrial PLC I/O modules.
For engineers reviewing the M30291FAVHP#UTQ datasheet, M30291FAVHP#UTQ pinout, M30291FAVHP#UTQ application, or M30291FAVHP#UTQ equivalent, key selection considerations include its 100-pin LQFP package, CAN interface timing compliance (ISO 11898-1), 3.0–5.5 V supply range, and support for hardware watchdog and brown-out reset - all critical for deterministic real-time control in harsh environments.
Technical Context
The M30291FAVHP#UTQ implements the M16C CPU architecture with 16-bit data bus width and 24-bit address space, enabling direct access to its full 256 KB flash and 16 KB RAM without banking. Its clock system integrates main crystal oscillator (1–20 MHz), sub-oscillator (32.768 kHz), on-chip oscillator, and PLL for flexible frequency synthesis up to 20 MHz CPU clock.
Peripheral integration includes one CAN controller (with 32 message objects, programmable bit timing, and loopback self-test mode), six 16-bit timer channels (including PWM output and input capture), 12-bit ADC with 16 channels and 1.2 μs conversion time, and dual UART/SIO interfaces supporting asynchronous and synchronous protocols.

FAQ
What is the maximum operating frequency of the M30291FAVHP#UTQ?
The M30291FAVHP#UTQ operates at a maximum CPU clock frequency of 20 MHz, achieved via internal PLL multiplication of the main crystal oscillator input (1–20 MHz range). This frequency is guaranteed across the full industrial temperature range (−40°C to +85°C) and supply voltage range (3.0 V to 5.5 V), with timing parameters validated in Renesas' official hardware manual Rev.1.12.
Does the M30291FAVHP#UTQ support CAN FD or only classical CAN 2.0B?
The M30291FAVHP#UTQ supports only CAN 2.0B (ISO 11898-1), not CAN FD. Its integrated CAN controller implements standard 11-bit and 29-bit identifier frames, programmable bit timing, and hardware message filtering - but lacks the variable data length, bit rate switching, and CRC enhancements defined in CAN FD. For CAN FD capability, consider Renesas' RA6M4 or RH850/F1K families instead.
What debug interface does the M30291FAVHP#UTQ use, and is JTAG supported?
The M30291FAVHP#UTQ uses the Renesas E8/E8a debug interface via dedicated pins (BKGD, RES#), not IEEE 1149.1 JTAG. This interface supports full real-time debugging including breakpoints, memory read/write, register inspection, and trace - but requires Renesas-compatible debuggers such as E8a or E2 Lite. JTAG is not implemented on this device; attempting JTAG connection will not yield functional access.
Is the M30291FAVHP#UTQ qualified for automotive applications?
No, the M30291FAVHP#UTQ is not AEC-Q100 qualified and is designated for "Standard" quality grade per Renesas' classification - intended for industrial, office, and consumer equipment. It is not recommended for automotive powertrain or chassis systems. For automotive-grade alternatives, refer to Renesas' RL78/F1x or RH850/P1x series with explicit AEC-Q100 certification and extended temperature support.
What is the endurance and data retention specification for the on-chip flash memory in M30291FAVHP#UTQ?
The on-chip flash memory in M30291FAVHP#UTQ is rated for 100,000 write/erase cycles and guarantees 20 years of data retention at +85°C ambient temperature. These specifications are verified per JEDEC JESD22-A117 and published in Renesas' M16C/29 Group hardware manual. Endurance applies to individual sectors; wear leveling must be implemented in firmware if uniform usage across flash is required.
