Renesas M30622SPFP#U5C

Overview

M30622SPFP#U5C 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 QFP (PRQP0100JB-A) package. It delivers 91 instructions, executes at 41.7 ns minimum instruction time (24 MHz BCLK), and integrates 4 KB RAM, 10-bit A/D converter (26 channels), dual 8-bit D/A converters, two DMAC channels, and I²C/IEBus/UART serial interfaces - enabling real-time control in industrial motor drives and office equipment.

For engineers reviewing the M30622SPFP#U5C datasheet, M30622SPFP#U5C pinout, M30622SPFP#U5C application, or M30622SPFP#U5C equivalent, key selection criteria include its ROM-less architecture for external code loading, -20°C to +85°C operating ambient temperature, lead-free U5 product code compliance, and compatibility with M16C/62P Group development tools and peripheral firmware libraries.

Technical Context

The M30622SPFP#U5C implements the M16C/60 Series 16-bit CISC CPU core with 1 MB address space and supports single-chip mode only. Its clock system includes main/subclock generation circuits, on-chip oscillator, and PLL synthesizer - enabling flexible timing configurations across 10 MHz and 24 MHz operation points while maintaining VCC1 = 3.0–5.5 V supply tolerance.

Peripheral integration includes Timer A (16-bit × 5 channels), Timer B (16-bit × 6 channels), three-phase motor control circuit, CCITT-CRC calculation unit, 15-bit watchdog timer with prescaler, and interrupt controller supporting 29 internal + 5 external sources at 7 priority levels - all optimized for deterministic response in closed-loop industrial control systems.

FAQ

What is the memory configuration of the M30622SPFP#U5C?

The M30622SPFP#U5C is a ROM-less device with 4 KB of on-chip RAM. It relies on external memory (e.g., SPI Flash or parallel NOR) for program storage and execution. This architecture supports flexible firmware updates and multi-image boot schemes, distinguishing it from mask ROM or flash-based variants in the M16C/62P family such as M30622F8PFP#U5C.

Does the M30622SPFP#U5C support I²C and IEBus simultaneously?

Yes, the M30622SPFP#U5C supports both I²C bus and IEBus protocols within its three-channel serial interface block. One channel operates as I²C/IEBus selectable via register configuration, enabling interoperability with legacy NEC automotive subsystems (IEBus) and standard sensors (I²C) without external protocol translators.

What is the significance of the "U5" suffix in M30622SPFP#U5C?

The "U5" suffix in M30622SPFP#U5C denotes a lead-free product code compliant with RoHS directives, specifying 1,000 program/erase cycles for user ROM areas and -20°C to +85°C operating ambient temperature. It corresponds to the package PRQP0100JB-A and confirms qualification for industrial-grade reliability per Renesas' Standard quality grade classification.

Can the M30622SPFP#U5C operate at 24 MHz with 3.3 V supply?

Yes, the M30622SPFP#U5C supports 24 MHz operation with VCC1 = 3.3 V to 5.5 V, achieving a minimum instruction execution time of 41.7 ns. Power consumption under this condition is 14 mA at 5 V and proportionally lower at 3.3 V, validated per the Electrical Characteristics table in the M16C/62P Group hardware manual Rev. 2.41.

How many I/O pins does the M30622SPFP#U5C provide?

The M30622SPFP#U5C provides 87 general-purpose I/O pins plus one dedicated input-only pin, consistent with the 100-pin QFP (PRQP0100JB-A) variant of the M16C/62P Group. These pins support multiplexed peripheral functions including timers, serial interfaces, and analog inputs - all configurable via port control registers without external glue logic.
