Renesas M30624FGPGP#U7C

Overview

M30624FGPGP#U7C 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 - used in industrial motor control and home appliance subsystems.

For engineers reviewing the M30624FGPGP#U7C datasheet, M30624FGPGP#U7C pinout, M30624FGPGP#U7C application, or M30624FGPGP#U7C equivalent, this page delivers verified specifications, package mapping to 100-pin LQFP, functional alternatives, and design-critical timing/peripheral details for OA, industrial, and automotive-qualified embedded systems.

Technical Context

The M30624FGPGP#U7C implements a single-chip 16-bit architecture with memory-mapped I/O, four clock generation circuits (main clock, subclock, on-chip oscillator, PLL synthesizer), and integrated peripherals including dual DMAC channels, CCITT-CRC calculation, and a 15-bit watchdog timer with prescaler. Its address space spans 1 MB (expandable to 4 MB).

It integrates two 8-bit D/A converters, a three-phase motor control circuit, five 16-bit Timer A channels, six 16-bit Timer B channels, and supports both single-chip and memory expansion modes - enabling real-time control of multi-axis motion and sensor-rich embedded systems without external bus logic.

FAQ

What is the maximum operating frequency and corresponding instruction execution time for M30624FGPGP#U7C?

M30624FGPGP#U7C operates at a maximum BCLK 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 confirmed in Table 1.2 of the official Renesas M16C/62P Group datasheet Rev.2.41. The CPU maintains deterministic performance across its full voltage and temperature range.

Does M30624FGPGP#U7C support IEBus communication, and what is its implementation level?

Yes, M30624FGPGP#U7C integrates a full hardware IEBus controller compliant with NEC's IEBus standard (registered trademark), supporting 200 kbps data rates and automatic frame formatting. This is documented in Table 1.1 and Table 1.2 under "Serial Interface" for both 100-pin M16C/62P and M16C/62PT variants - eliminating need for external protocol translators.

What are the Flash memory endurance specifications for M30624FGPGP#U7C, and how do they vary by memory region?

M30624FGPGP#U7C Flash endurance is region-specific: 1,000 program/erase cycles for user ROM area (excluding blocks A and 1), and 10,000 cycles for block A and block 1 - as defined in Table 1.8 (Product Code U7) and confirmed in Renesas documentation. This enables safe use of block A for bootloader storage and frequent updates to user application areas.

Which package type and pin count does M30624FGPGP#U7C use, and is it RoHS-compliant?

M30624FGPGP#U7C uses the PLQP0100KB-A package: a 100-pin plastic LQFP with 0.5 mm pitch and lead-free finish (RoHS-compliant). This is explicitly stated in Table 1.5 and Figure 1.3 of the Renesas datasheet, and the "U7" product code in the part marking confirms lead-free construction per Table 1.8.

How does the voltage detection circuit function in M30624FGPGP#U7C, and is it enabled by default?

The voltage detection circuit in M30624FGPGP#U7C is an optional feature available only on M16C/62P (not M16C/62PT) variants and must be enabled via configuration bits during programming - it is not active by default. Its presence is noted in Table 1.2 as "Available (option)" and requires external resistor network setup per Renesas Hardware Manual.
