Overview

M30624FGPGP#U9C from Renesas Electronics is a 16-bit Flash-based microcontroller in the M16C/62P Group, built on the M16C/60 Series CPU core. It features 256 KB + 4 KB Flash ROM, 20 KB RAM, operates at up to 24 MHz (41.7 ns min instruction time), and supports I²C, UART, IEBus, and 10-bit A/D conversion across 26 channels - deployed in industrial motor control and office equipment.

For engineers reviewing the M30624FGPGP#U9C datasheet, M30624FGPGP#U9C pinout, M30624FGPGP#U9C application, or M30624FGPGP#U9C equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C operating range, 1,000/10,000-cycle Flash endurance (blocks A/1), dual DMAC channels, and integrated three-phase motor control circuitry.

Technical Context

The M30624FGPGP#U9C implements the M16C/60 Series 16-bit CISC CPU core with 91 basic instructions and supports single-chip, memory expansion, and microprocessor modes. Its memory map provides 1 MB address space (expandable to 4 MB), with on-chip Flash organized into user ROM and protected blocks A and 1 for differentiated erase cycles.

Peripheral integration includes two 16-bit multifunction timer groups (Timer A: 5 channels; Timer B: 6 channels), a CCITT-CRC calculation circuit, PLL synthesizer with built-in feedback resistor, and voltage detection circuit (option-enabled). The device uses dual supply rails (VCC1 = 4.0–5.5 V, VCC2 = VCC1) and supports wait/stop low-power modes down to 2.0 µA and 0.8 µA respectively.

FAQ

What is the Flash memory organization and endurance rating for M30624FGPGP#U9C?

M30624FGPGP#U9C contains 256 KB + 4 KB Flash ROM partitioned into user ROM area and protected blocks A and 1. Per Renesas documentation, the user ROM area supports 1,000 program/erase cycles, while blocks A and 1 are rated for 10,000 cycles - enabling reliable bootloader and calibration storage. The U9 product code confirms lead-free packaging and -20°C to +85°C operating range.

Does M30624FGPGP#U9C support IEBus, and what hardware is required?

Yes, M30624FGPGP#U9C natively supports IEBus (a NEC-proprietary automotive serial bus) through dedicated port pins (e.g., P20–P27) and internal protocol logic. No external transceiver is needed - only passive termination resistors and proper layout per Renesas AN1001. This capability is confirmed in the M16C/62P Group hardware manual Rev.2.41.

What power supply configuration does M30624FGPGP#U9C require?

M30624FGPGP#U9C requires dual supplies: VCC1 = 4.0–5.5 V for CPU and core logic, and VCC2 = VCC1 (not independently biased) for I/O ports. This configuration is mandatory per Table 1.2 and prevents latch-up or undefined behavior. Decoupling capacitors (0.1 µF ceramic near each VCC pin) are required per Renesas layout guidelines.

How many A/D input channels are accessible on M30624FGPGP#U9C, and what resolution do they provide?

M30624FGPGP#U9C integrates a single 10-bit successive-approximation A/D converter with 26 multiplexed input channels (AN0–AN25), mapped across ports P3–P7 and P10. Conversion time is 1.5 µs typical at 24 MHz BCLK. All channels share one sample-and-hold circuit, and the result is stored in 16-bit registers for precision post-processing.

Is M30624FGPGP#U9C pin-compatible with other M16C/62P family members in 100-pin LQFP?

M30624FGPGP#U9C uses the PLQP0100KB-A package (100-pin LQFP), matching pinout with other 100-pin M16C/62P variants (e.g., M30622F8PGP, M30620FCPGP). However, peripheral enablement differs - for example, IEBus is only active on specific port pins and requires correct mode register settings. Full functional compatibility requires verifying memory size, Flash block layout, and option bit configuration per device.
