Renesas M30620SPFP#U5C

Overview

M30620SPFP#U5C from Renesas Electronics is a ROM-less 16-bit microcontroller in the M16C/62P Group, built on the M16C/60 Series CPU core and packaged in a 100-pin plastic QFP (PRQP0100JB-A). It features 10 KB RAM, 91 basic instructions, 24 MHz max BCLK operation at 3.3–5.5 V, and integrated peripherals including dual 16-bit timer groups, 3-channel serial I/O (UART/I²C/IEBus), 10-bit 26-channel ADC, dual 8-bit DACs, 2-channel DMAC, and CCITT-CRC circuit - enabling real-time control in industrial motor drives and office equipment.

For engineers reviewing the M30620SPFP#U5C datasheet, M30620SPFP#U5C pinout, M30620SPFP#U5C application, or M30620SPFP#U5C equivalent, this part supports single-chip mode only, requires external program memory, operates across –20°C to +85°C, and delivers 41.7 ns minimum instruction execution time at 24 MHz - critical for deterministic timing in embedded motion control and communication interface firmware.

Technical Context

The M30620SPFP#U5C implements the M16C/60 Series 16-bit CISC CPU core with 1 MB address space and memory expansion capability. Its peripheral set includes Timer A (16-bit × 5 channels) and Timer B (16-bit × 6 channels), three-phase motor control logic, and clock-synchronous serial I/O supporting UART, I²C bus, and IEBus protocols - all mapped to dedicated internal registers and interrupt vectors.

Power management includes wait and stop modes achieving 1.8 µA and 0.7 µA current draw at 3 V, respectively, with oscillation stop detection for main clock failure recovery. The device uses dual supply rails (VCC1 = 3.0–5.5 V, VCC2 = 2.7 V to VCC1) and integrates PLL frequency synthesis, on-chip oscillator, and subclock generation circuits for flexible clock source selection.

FAQ

What is the memory architecture of the M30620SPFP#U5C?

The M30620SPFP#U5C is a ROM-less microcontroller with no on-chip program memory. It contains 10 KB of on-chip RAM for data and stack storage, and relies entirely on external memory (e.g., parallel NOR Flash or SRAM) for program code execution. This architecture enables flexible firmware updates and multi-version deployment without mask ROM commitment.

Does the M30620SPFP#U5C support I²C and IEBus simultaneously?

Yes, the M30620SPFP#U5C supports both I²C bus and IEBus protocols concurrently through shared pins on Port P3. The hardware includes dedicated I²C control registers and IEBus timing generators, allowing independent initialization and operation of both interfaces - commonly used for connecting temperature sensors (I²C) and automotive audio modules (IEBus).

What is the maximum operating frequency and voltage range for the M30620SPFP#U5C?

The M30620SPFP#U5C operates at up to 24 MHz BCLK with VCC1 = 3.0–5.5 V and VCC2 = 2.7 V to VCC1. At 24 MHz, minimum instruction execution time is 41.7 ns. For 10 MHz operation, supply voltage extends down to 2.7 V, enabling compatibility with battery-powered or low-voltage industrial systems.

How does the three-phase motor control circuit function in the M30620SPFP#U5C?

The M30620SPFP#U5C integrates dedicated three-phase motor control logic that generates complementary PWM outputs with programmable dead-time insertion. It synchronizes Timer A and Timer B channels to produce six-phase gate drive signals - eliminating external logic and reducing timing skew in BLDC or PMSM inverter designs.

Is the M30620SPFP#U5C RoHS-compliant and lead-free?

Yes, the M30620SPFP#U5C carries product code U5, indicating a lead-free (Pb-free) package per JEDEC J-STD-609. It complies with EU RoHS Directive 2011/65/EU and is manufactured using environmentally compliant processes - verified by Renesas' material declarations and packaging specifications.
