Renesas M30624SPFP#U3C

Overview

M30624SPFP#U3C from Renesas Electronics is a ROM-less 16-bit microcontroller based on the M16C/60 Series CPU core, packaged in a 100-pin plastic QFP (PRQP0100JB-A). It delivers 91 instructions, executes at 41.7 ns minimum instruction time (24 MHz BCLK), and integrates 20 KB RAM, dual 8-bit DACs, 10-bit 26-channel ADC, two DMAC channels, and three serial interfaces including UART and I²C - enabling real-time control in office equipment and industrial automation systems.

For engineers reviewing the M30624SPFP#U3C datasheet, M30624SPFP#U3C pinout, M30624SPFP#U3C application, or M30624SPFP#U3C equivalent, key selection criteria include its ROM-less architecture requiring external program memory, 100-pin QFP package with VCC1/VCC2 dual-supply support (4.0–5.5 V), -40°C to +85°C operating range, and compatibility with M16C/62P Group development tools and peripheral libraries.

Technical Context

The M30624SPFP#U3C implements the M16C/60 Series 16-bit CISC CPU core with 1 MB address space and single-chip operation mode. Its clock system includes main/subclock generation circuits, on-chip oscillator, and PLL synthesizer - supporting flexible timing configurations for synchronous peripherals.

It features a multifunction timer subsystem (Timer A: 16-bit ×5 channels; Timer B: 16-bit ×6 channels), three-phase motor control circuitry, CCITT-CRC calculation unit, and 15-bit watchdog timer with prescaler - all coordinated via a 7-level priority interrupt controller servicing 29 internal, 5 external, and 4 software sources.

FAQ

What is the maximum operating frequency of the M30624SPFP#U3C?

The M30624SPFP#U3C supports a maximum BCLK frequency of 24 MHz, achieving a minimum instruction execution time of 41.7 ns under VCC1 = 4.0–5.5 V conditions. This timing is validated per the M16C/62P Group datasheet Rev.2.41 and applies directly to the M30624SPFP#U3C in its specified 100-pin QFP configuration.

Does the M30624SPFP#U3C include on-chip flash memory?

No, the M30624SPFP#U3C is a ROM-less device - it contains no on-chip program memory and requires external Flash or EEPROM for firmware storage. This is confirmed by its "S" prefix in the part numbering scheme (per Figure 1.3) and explicit listing in Table 1.5 as a ROM-less version with 20 KB RAM only.

What is the operating temperature range for the M30624SPFP#U3C?

The M30624SPFP#U3C is rated for -40°C to +85°C ambient operation, as indicated by its U3 product code in Table 1.8 (lead-free, -40°C to 85°C temperature range). This specification is consistent across all M16C/62P ROM-less variants in the 100-pin QFP package.

Which serial interfaces are supported by the M30624SPFP#U3C?

The M30624SPFP#U3C supports three serial channels: one UART, one clock-synchronous interface, and one I²C/IEBus channel - as documented in Table 1.2 for the 100-pin M16C/62P variant. All three are accessible on dedicated pins and configurable via on-chip registers without external logic.

Is the M30624SPFP#U3C pin-compatible with other M16C/62P family members?

Yes, the M30624SPFP#U3C shares the same 100-pin PRQP0100JB-A QFP package and pin assignment with other M16C/62P 100-pin variants (e.g., M30624FGPFP#U3C), including identical power, clock, reset, and I/O pin locations - enabling hardware reuse across ROM-less and flash-based designs.
