Product details
Overview
M30302SPGP#U3 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 LQFP (PLQP0100KB-A) package. 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/B), and three UART/I²C/IEBus-capable serial interfaces - enabling real-time control in industrial motor drives and embedded instrumentation.
For engineers reviewing the M30302SPGP#U3 datasheet, M30302SPGP#U3 pinout, M30302SPGP#U3 application, or M30302SPGP#U3 equivalent, key selection criteria include its ROM-less architecture requiring external program memory, -40°C to +85°C operating temperature range, and support for 8-/16-bit external bus expansion with CS0–CS3 chip-select outputs.
Technical Context
The M30302SPGP#U3 implements the M16C/60 Series 16-bit CISC CPU core with 91 basic instructions and 1 Mbyte linear address space. Its memory subsystem supports external program storage via 20-bit address bus (A0–A19) and configurable 8-/16-bit data bus (D0–D15), controlled by WRH/BHE, WRL/WR, RD, ALE, HOLD/HLDA, and RDY signals.
Peripheral integration includes two independent DMAC channels, CCITT-CRC calculation circuit, 15-bit watchdog timer with prescaler, and interrupt controller supporting 20 internal + 7 external sources across 7 priority levels. Clock generation uses dual oscillators: main (XIN/XOUT, up to 16 MHz) and sub (XCIN/XCOUT, 32 kHz), both with built-in feedback resistors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLGFB#30 | RL78/G13 16-bit MCU with 128 KB Flash, integrated debug interface, lower active current (120 μA/MHz) | Flash-based, self-programmable; lacks IEBus but adds LIN and DMA with scatter-gather support | Select for new designs requiring field firmware updates and lower power; not drop-in due to different pinout and peripheral register map |
| HD64F3687FP | H8/300H 16-bit MCU with 128 KB ROM, 8 KB RAM, 100-pin QFP, same legacy Renesas architecture | Mask-ROM only; no A/D trigger (ADTRG), fewer serial channels (2), no IEBus support | Consider for cost-sensitive, high-volume legacy replacements where external memory interface and IEBus are unused |
Compared with R5F100PLGFB#30 and HD64F3687FP, the M30302SPGP#U3 uniquely combines ROM-less flexibility, IEBus protocol support for Japanese automotive subsystems, and hardware CRC acceleration - making it irreplaceable in legacy industrial equipment upgrades requiring external program storage and specific bus compatibility.

FAQ
What is the package type and pin count of the M30302SPGP#U3?
The M30302SPGP#U3 uses a 100-pin LQFP package designated PLQP0100KB-A (also known as 100P6Q-A), with lead-free finish and industrial temperature grading (-40°C to +85°C). This matches the GP suffix in the part number and is distinct from the FP variant (PRQP0100JB-A, 100P6S-A).
Does the M30302SPGP#U3 include on-chip program memory?
No, the M30302SPGP#U3 is a ROM-less device (denoted by "S" in the part number prefix). It requires external program memory - such as parallel Flash or EPROM - connected via its 20-bit address and 16-bit data bus. The U3 product code confirms lead-free packaging and -40°C to +85°C operation.
What serial communication protocols does the M30302SPGP#U3 support?
The M30302SPGP#U3 supports UART, clock-synchronous serial, I²C Bus (1 channel), and IEBus (1 channel) across its three serial interface units. IEBus support is particularly valuable for legacy Japanese automotive and audio equipment integration, while I²C enables sensor and EEPROM interfacing.
How does the M30302SPGP#U3 handle analog-to-digital conversion?
The M30302SPGP#U3 integrates a 10-bit A/D converter with 18 input channels: eight standard (AN0–AN7), eight auxiliary (AN0_0–AN0_7), plus two extended inputs (ANEX0, ANEX1). Conversion is triggered either internally or externally via the ADTRG pin, enabling precise synchronization with timer events or external signals.
What are the power supply requirements for the M30302SPGP#U3?
The M30302SPGP#U3 requires two separate 2.7–5.5 V supplies: VCC1 and VCC2 must be equal (VCC1 = VCC2), plus AVCC (analog supply, tied to VCC1) and AVSS (analog ground, tied to VSS). Power consumption is 10 mA at 5 V/16 MHz, dropping to 0.7 μA in stop mode with 3 V/32 kHz sub-clock active.
