Renesas M30620SPFP#U5

Overview

M30620SPFP#U5 from Renesas Electronics is a ROM-less 16-bit single-chip microcomputer based on the M16C/60 Series CPU core, packaged in a 100-pin plastic QFP (PRQP0100JB-A). It delivers 41.7 ns minimum instruction execution time at 24 MHz BCLK, integrates 10 Kbytes of RAM, supports 1 Mbyte address space, and features dual-channel DMAC, 10-bit 26-channel A/D converter, and I²C/IEBus/UART serial interfaces - enabling real-time control in industrial motor drives and office equipment.

For engineers reviewing the M30620SPFP#U5 datasheet, M30620SPFP#U5 pinout, M30620SPFP#U5 application, or M30620SPFP#U5 equivalent, key selection criteria include its ROM-less architecture requiring external program memory, -20°C to +85°C operating ambient temperature, lead-free packaging (U5 code), and compatibility with M16C/62P Group development tools and peripheral drivers.

Technical Context

The M30620SPFP#U5 implements the M16C/60 Series 16-bit CISC CPU core with 91 basic instructions and supports single-chip, memory expansion, and microprocessor operating modes. Its memory map provides 1 Mbyte linear address space expandable to 4 Mbytes via memory space expansion function, and it executes instructions directly from external memory since no on-chip ROM is present.

Peripheral integration includes Timer A (16-bit × 5 channels) and Timer B (16-bit × 6 channels) for precise timing and three-phase motor control, two UART/clock-synchronous serial I/O channels, CCITT-CRC calculation circuit, 15-bit watchdog timer with prescaler, and PLL-based clock generation with main/subclock oscillators and on-chip oscillator - all operating under dual supply rails (VCC1 = 3.0–5.5 V, VCC2 = 2.7 V to VCC1).

FAQ

What is the memory configuration of the M30620SPFP#U5?

The M30620SPFP#U5 is a ROM-less microcontroller with no on-chip program memory, relying entirely on external memory for code execution. It integrates 10 Kbytes of on-chip SRAM for data and stack storage. This architecture enables field firmware updates and eliminates mask ROM NRE charges, making M30620SPFP#U5 ideal for prototyping and low-volume production runs where flexibility outweighs fixed-ROM cost advantages.

Does the M30620SPFP#U5 support I²C and IEBus simultaneously?

Yes, the M30620SPFP#U5 supports both I²C bus and IEBus protocols concurrently within its 3-channel serial interface block. One channel operates as UART or clock-synchronous I/O, another as I²C bus (compliant with Philips I²C specification), and the third as IEBus (NEC proprietary vehicle infotainment bus). This allows M30620SPFP#U5 to serve as a bridge between legacy automotive subsystems and modern sensor networks in industrial gateway applications.

What is the significance of the "#U5" suffix in M30620SPFP#U5?

The "#U5" suffix in M30620SPFP#U5 denotes the product code per Renesas' marking convention: "U" indicates lead-free packaging, and "5" specifies -20°C to +85°C operating ambient temperature range. This distinguishes it from lead-containing (D-series) or extended-temp (U7/U9) variants. The M30620SPFP#U5 thus meets RoHS compliance requirements and targets commercial/industrial environments - not automotive or military-grade applications.

Can the M30620SPFP#U5 operate from a single 3.3 V supply?

No - the M30620SPFP#U5 requires two separate supply domains: VCC1 (3.0–5.5 V for CPU and core logic) and VCC2 (2.7 V to VCC1 for I/O ports). While VCC1 may be set to 3.3 V, VCC2 must be supplied independently and cannot be tied directly to VCC1 unless both are regulated to the same nominal voltage with adequate decoupling. This dual-rail design enables mixed-voltage interfacing but prohibits true single-supply operation.

Is there hardware support for CRC-16 in the M30620SPFP#U5?

Yes, the M30620SPFP#U5 includes a dedicated CCITT-CRC hardware calculation circuit implementing the X¹⁶+X¹²+X⁵+1 polynomial. It operates autonomously on serial data streams or memory blocks without CPU intervention, generating CRC values used for error detection in I²C, UART, or custom protocol frames. This offloads checksum computation from the M16C/60 core, preserving deterministic timing in M30620SPFP#U5-based communication subsystems.
