Renesas M30620SPGP#U3C

Overview

M30620SPGP#U3C from Renesas Electronics is a ROM-less 16-bit single-chip microcomputer based on the M16C/60 Series CPU core, housed in a 100-pin plastic LQFP (PLQP0100KB-A) package. It delivers 91 instructions, executes at 41.7 ns minimum instruction time (24 MHz BCLK), and integrates dual DMAC channels, 10-bit A/D converter with 26 channels, two 8-bit D/A converters, and I²C/IEBus/UART serial interfaces. It targets industrial control and embedded systems requiring flexible firmware loading and real-time peripheral management.

FAQ

What is the memory configuration of the M30620SPGP#U3C?

The M30620SPGP#U3C is a ROM-less microcontroller with no internal program memory. It includes 10 KB of on-chip RAM for data and stack storage. Firmware must be loaded externally via UART, I²C, or parallel interface using a custom bootloader - a key differentiator from flash-equipped variants like M30620FCPGP#U3C. This architecture supports field-upgradable firmware and eliminates mask ROM NRE charges.

Which package and pin count does M30620SPGP#U3C use?

M30620SPGP#U3C uses a 100-pin plastic LQFP package (PLQP0100KB-A), measuring 14 mm × 14 mm with 0.5 mm pitch. It is RoHS-compliant and marked with product code U3, indicating lead-free finish and -40°C to +85°C operating temperature range. This package provides 87 usable I/O pins plus dedicated power, clock, and reset terminals.

Does M30620SPGP#U3C support IEBus, and what is its role?

Yes, M30620SPGP#U3C supports IEBus (Inter-Equipment Bus) as a primary serial interface - a legacy automotive protocol standardized by NEC. It operates as an IEBus master or slave, enabling communication with door modules, climate controllers, and audio units in Japanese vehicle platforms. The integrated hardware controller offloads protocol timing and CRC generation from the CPU.

What are the power supply requirements for M30620SPGP#U3C?

M30620SPGP#U3C requires two independent supplies: VCC1 (3.0–5.5 V) for core/digital logic and VCC2 (2.7 V to VCC1) for analog peripherals including A/D and D/A converters. This dual-rail design enables noise isolation between digital switching and precision analog functions. Typical active current is 14 mA at 5 V/24 MHz; stop mode draws just 0.7 µA.

How does the three-phase motor control circuit function in M30620SPGP#U3C?

The M30620SPGP#U3C integrates dedicated hardware for three-phase inverter control, including complementary PWM output generation, programmable dead-time insertion, and fault protection inputs (e.g., overcurrent shutdown). It synchronizes Timer A/B channels to produce six-phase gate drive signals directly - eliminating external gate driver logic and reducing BOM count in BLDC/PMSM motor drives.
