Renesas M30624SPGP#U5C

Overview

M30624SPGP#U5C from Renesas Electronics is a ROM-less 16-bit microcontroller based on the M16C/60 CPU core, packaged in a 100-pin LQFP (PLQP0100KB-A). It delivers 91 instructions, executes at 41.7 ns minimum instruction time (24 MHz BCLK), and integrates 20 KB RAM, dual 8-bit D/A converters, 10-bit A/D converter with 26 channels, and two DMAC channels - enabling real-time control in industrial motor drives and embedded instrumentation.

For engineers reviewing the M30624SPGP#U5C datasheet, M30624SPGP#U5C pinout, M30624SPGP#U5C application, or M30624SPGP#U5C equivalent, key selection considerations include its ROM-less architecture requiring external program memory, -20°C to +85°C operating range (U5 product code), lead-free LQFP package, and compatibility with IEBus/I²C serial interfaces for automotive body control and home appliance HMI subsystems.

Technical Context

The M30624SPGP#U5C implements the M16C/60 Series CPU core with single-chip operation mode only, supporting 1 MB address space expandable to 4 MB via memory space expansion function. Its clock system includes main/subclock generation circuits, on-chip oscillator, and PLL synthesizer - all equipped with built-in feedback resistors for simplified design.

Peripheral integration includes Timer A (16-bit × 5 channels) and Timer B (16-bit × 6 channels), three-phase motor control circuitry, UART + clock-synchronous serial I/O (3 channels), CCITT-CRC calculation unit, and 15-bit watchdog timer with prescaler - targeting deterministic timing-critical applications such as HVAC fan control and digital power supply supervision.

FAQ

What is the memory architecture of the M30624SPGP#U5C?

The M30624SPGP#U5C is a ROM-less microcontroller with no on-chip program memory. It contains 20 KB of on-chip RAM for data and stack usage, requiring external Flash or EEPROM for program storage. This architecture supports flexible firmware updates and multi-product platform reuse without mask ROM NRE charges or long lead times - a key advantage for M30624SPGP#U5C in rapidly evolving industrial designs.

Does the M30624SPGP#U5C support IEBus communication?

Yes, the M30624SPGP#U5C natively supports IEBus (Inter-Equipment Bus) as part of its serial interface capabilities. It implements IEBus protocol handling in hardware, eliminating the need for an external transceiver IC in automotive body control modules. This feature is confirmed in the M16C/62P Group datasheet Rev.2.41 and applies directly to the M30624SPGP#U5C variant - distinguishing it from later RL78 or RX family parts that lack native IEBus support.

What is the operating temperature range for the M30624SPGP#U5C?

The M30624SPGP#U5C has an operating ambient temperature range of -20°C to +85°C, indicated by the "U5" product code per Table 1.8 of the M16C/62P Group datasheet. This rating applies to the lead-free 100-pin LQFP package (PLQP0100KB-A) and is validated for continuous operation under specified supply voltage and clock conditions - making M30624SPGP#U5C suitable for commercial and industrial environments but not extended-temperature automotive under-hood use.

Can the M30624SPGP#U5C be used for three-phase motor control?

Yes, the M30624SPGP#U5C includes a dedicated three-phase motor control circuit integrated into its peripheral set. This hardware block provides complementary PWM outputs with programmable dead-time insertion, fault input monitoring, and synchronization with ADC sampling - enabling efficient BLDC or PMSM commutation without consuming CPU cycles. The M30624SPGP#U5C's 26-channel ADC and dual DACs further support current/voltage sensing and reference generation required in motor drive applications.

What package type does the M30624SPGP#U5C use?

The M30624SPGP#U5C uses a 100-pin plastic LQFP package designated PLQP0100KB-A (equivalent to 100P6Q-A), with 0.5 mm lead pitch and RoHS-compliant lead-free finish. This package is confirmed in Table 1.5 (Product List) and Figure 1.3 of the M16C/62P Group datasheet Rev.2.41. Its footprint is compatible with standard PCB assembly processes and supports thermal dissipation requirements up to 14 mA active current at 5 V - critical for sustained operation in M30624SPGP#U5C-based motor controllers.
