Product details
Overview
M30302SPFP#U3 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 62.5 ns minimum instruction execution time at 16 MHz, integrates a 10-bit 18-channel A/D converter, dual 16-bit multifunction timers (Timer A and Timer B), three UART/I²C/IEBus-capable serial interfaces, and two-channel DMAC - enabling real-time control in industrial motor drives and embedded instrumentation.
For engineers reviewing the M30302SPFP#U3 datasheet, M30302SPFP#U3 pinout, M30302SPFP#U3 application, or M30302SPFP#U3 equivalent, key selection considerations include its ROM-less architecture requiring external program memory, 6 KB on-chip RAM, -40°C to +85°C operating temperature range, and support for both 8- and 16-bit external bus configurations via BYTE pin control.
Technical Context
The M30302SPFP#U3 implements the M16C/60 Series CPU core with 91 basic instructions and supports single-chip, memory expansion, and microprocessor operation modes. Its memory space spans 1 Mbyte, with no internal ROM but 6 KB of on-chip RAM mapped across dedicated address regions.
It features dual clock generation circuits (main XIN/XOUT and sub XCIN/XCOUT), CCITT-CRC calculation hardware, a 15-bit watchdog timer with prescaler, and interrupt capability from 20 internal, 7 external, and 4 software sources across 7 priority levels - all optimized for deterministic response in closed-loop control systems.

FAQ
What is the memory configuration of the M30302SPFP#U3?
The M30302SPFP#U3 is a ROM-less device with no internal program memory, featuring 6 KB of on-chip RAM for data and stack storage. Firmware must be loaded from external memory (e.g., SPI Flash or parallel EEPROM) at boot via the external bus interface. This architecture supports field updates and eliminates mask ROM NRE charges.
Does the M30302SPFP#U3 support IEBus communication?
Yes, the M30302SPFP#U3 supports IEBus (a registered trademark of NEC Electronics) on its serial interface channels. One channel is explicitly configured for IEBus operation per the M16C/30P Group specification, enabling interoperability with legacy Japanese automotive and audio subsystems that rely on this protocol.
What package type and pin count does the M30302SPFP#U3 use?
The M30302SPFP#U3 uses the PRQP0100JB-A package - a 100-pin plastic quad flat pack (QFP), also designated 100P6S-A. It is lead-free and RoHS-compliant, with 0.65 mm pin pitch and standard surface-mount footprint compatible with automated assembly processes.
How does the M30302SPFP#U3 handle clock sources?
The M30302SPFP#U3 integrates two independent clock generation circuits: a main oscillator (XIN/XOUT, 1–16 MHz) for CPU and high-speed peripherals, and a sub-oscillator (XCIN/XCOUT, 32.768 kHz) for RTC and ultra-low-power wake-up. Both include built-in feedback resistors, eliminating external components.
What is the operating temperature range for the M30302SPFP#U3?
The M30302SPFP#U3 is rated for -40°C to +85°C ambient operation, as indicated by the U3 product code in its marking. This industrial-grade temperature range qualifies it for deployment in factory automation, outdoor instrumentation, and commercial HVAC systems without derating.
