Product details
Overview
M30291FCHP#U5A from Renesas Electronics is a 16-bit CMOS microcontroller in the M16C/29 Group, designed for embedded control in industrial and consumer systems. It features 256 KB on-chip flash memory, 16 KB RAM, a 16-MHz max CPU clock, and integrated peripherals including UART, I2C, 10-bit ADC, and PWM timers. It operates from 2.7 V to 5.5 V and targets motor control and sensor interface applications.
For engineers reviewing the M30291FCHP#U5A datasheet, M30291FCHP#U5A pinout, M30291FCHP#U5A application, or M30291FCHP#U5A equivalent, key selection criteria include its 100-pin LQFP package, 16-bit M16C core architecture, flash endurance (10,000 write/erase cycles), operating temperature range (−40°C to +85°C), and support for single-cycle instruction execution at 16 MHz.
Technical Context
The M30291FCHP#U5A implements the M16C/29 Group architecture with a 16-bit CISC CPU core, supporting both 8- and 16-bit data operations. It integrates a 10-bit, 16-channel ADC with conversion time as low as 1.2 μs, three 16-bit timer/counters with capture/compare and PWM output capability, and dual UART channels with automatic baud-rate detection.
Its clock system includes main clock (1–10 MHz crystal), sub-clock (32.768 kHz), on-chip oscillator (1 MHz), and PLL for internal CPU clock generation up to 16 MHz. Power management supports Normal, Wait, and Stop modes, with brown-out detection reset and low-voltage detection interrupt functionality.

Pinout & Package
The M30291FCHP#U5A is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad for enhanced heat dissipation in continuous-duty applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

FAQ
What is the maximum operating frequency of the M30291FCHP#U5A?
The M30291FCHP#U5A supports a maximum CPU clock frequency of 16 MHz, achieved using its on-chip PLL with an external 1–10 MHz crystal. This frequency is sustained across the full −40°C to +85°C operating temperature range and 2.7 V to 5.5 V supply voltage, enabling consistent real-time performance in industrial environments. The M30291FCHP#U5A achieves single-cycle instruction execution at this rate for critical timing-critical code sections.
Does the M30291FCHP#U5A support in-system programming (ISP)?
Yes, the M30291FCHP#U5A supports in-system programming via its on-chip boot ROM and dedicated serial interface (BSI). Firmware updates can be performed through UART0 without removing the device from the board, using Renesas' Flash Development Toolkit (FDT) or third-party compatible tools. This capability is fully implemented in the M30291FCHP#U5A and verified in the M16C/29 Group Hardware Manual Rev.1.12.
What is the ADC resolution and conversion speed of the M30291FCHP#U5A?
The M30291FCHP#U5A integrates a 10-bit successive approximation register (SAR) ADC with 16 input channels. Its minimum conversion time is 1.2 μs under typical conditions (VCC = 5 V, fAD = 16 MHz), delivering up to 833 kSPS throughput. This specification is confirmed in the Electrical Characteristics section of the M16C/29 Group Hardware Manual and applies directly to the M30291FCHP#U5A variant.
Is the M30291FCHP#U5A pin-compatible with other M16C/29 Group devices?
The M30291FCHP#U5A uses the standard 100-pin LQFP package shared across multiple M16C/29 Group members, including M30291FCHP#U5 and M30291FCHP#U5B. Pin assignments for power, reset, clocks, and core peripherals are identical; however, some alternate function mappings (e.g., IEBus vs. CAN) differ between variants. Full pin compatibility requires verification against the specific target part's pin description table in the M16C/29 Group Hardware Manual.
What industrial certifications or quality grades apply to the M30291FCHP#U5A?
The M30291FCHP#U5A is classified as a "Standard" quality grade product per Renesas' documentation, intended for industrial robots, machine tools, test equipment, and home appliances. It is not qualified for automotive AEC-Q100, medical, or aerospace applications. This grading is explicitly stated in Renesas' Quality Grade Notice and applies uniformly to all M16C/29 Group devices unless otherwise specified - which is not the case for the M30291FCHP#U5A.
