Renesas M30624FGPFP#U3C

Overview

M30624FGPFP#U3C from Renesas Electronics is a 16-bit Flash microcontroller in the M16C/62P Group, built on the M16C/60 Series CPU core and packaged in a 100-pin plastic QFP (PRQP0100JB-A). It integrates 256 KB + 4 KB Flash ROM, 20 KB RAM, a 10-bit 26-channel A/D converter, dual 8-bit D/A converters, and two DMAC channels. It operates at up to 24 MHz (41.7 ns min instruction time) with supply voltage 3.0–5.5 V and supports industrial temperature range (−40°C to +85°C), making it suitable for motor control and embedded industrial equipment.

FAQ

What is the maximum operating frequency of the M30624FGPFP#U3C?

The M30624FGPFP#U3C supports a maximum main clock frequency of 24 MHz, achieving a minimum instruction execution time of 41.7 ns under VCC1 = 3.3–5.5 V conditions. This timing is verified for stable operation across the full −40°C to +85°C industrial temperature range and enables deterministic real-time control in motor drive applications.

Does the M30624FGPFP#U3C include hardware support for motor control?

Yes, the M30624FGPFP#U3C integrates a dedicated three-phase motor control circuit that provides complementary PWM output generation, programmable dead-time insertion, and fault input handling. This hardware block offloads timing-critical functions from the CPU, enabling efficient implementation of BLDC and PMSM motor control without external gate driver logic.

What are the Flash memory endurance specifications for M30624FGPFP#U3C?

The M30624FGPFP#U3C Flash memory has region-specific endurance: 100 program/erase cycles for the entire array, 1,000 cycles for user ROM areas excluding block A and block 1, and 10,000 cycles for block A and block 1. These values are guaranteed under the U3 product code (lead-free, −40°C to +85°C) per Renesas documentation REJ03B0001-0241.

Which serial communication interfaces are available on the M30624FGPFP#U3C?

The M30624FGPFP#U3C provides three serial interface channels: one supports UART or clock-synchronous mode, another supports I²C bus (Philips standard), and the third supports IEBus (NEC standard). Two additional clock-synchronous-only channels are also available, enabling simultaneous communication with diverse peripherals including sensors, displays, and legacy automotive modules.

Is the M30624FGPFP#U3C pin-compatible with other M16C/62P family members?

Yes, the M30624FGPFP#U3C uses the PRQP0100JB-A (100P6S-A) package and shares identical pinout with all other 100-pin M16C/62P variants, including mask ROM and ROM-less versions. Signal mapping, power pin locations, and reset behavior are consistent across this package footprint, allowing direct substitution within the same PCB layout.
