Renesas M30302GCPGP#35

Overview

M30302GCPGP#35 from Renesas Electronics is a 16-bit single-chip microcomputer based on the M16C/60 Series CPU core, designed for embedded control in industrial and consumer equipment. It features 128 KB of one-time programmable flash memory, 10-bit 18-channel A/D conversion, dual 16-bit multifunction timers (Timer A/B), and three serial interfaces including UART, clock-synchronous I/O, and I²C bus. It operates at up to 16 MHz with 62.5 ns minimum instruction execution time and supports 100-pin LQFP packaging.

For engineers reviewing the M30302GCPGP#35 datasheet, M30302GCPGP#35 pinout, M30302GCPGP#35 application, or M30302GCPGP#35 equivalent, key selection criteria include its 128 KB one-time flash capacity, 18-channel analog input capability, support for external memory expansion via 20-bit address bus (A0–A19), and compatibility with both 3.0–5.5 V and 2.7–5.5 V supply ranges depending on clock frequency.

Technical Context

The M30302GCPGP#35 implements the M16C/60 Series CPU core with 91 basic instructions and executes code at 62.5 ns per instruction at 16 MHz (VCC = 3.0–5.5 V). Its memory architecture supports 1 Mbyte address space, with on-chip flash organized as a single programmable block and RAM sized at 6 KB.

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 circuits - main (XIN/XOUT) and sub (XCIN/XCOUT) - both with built-in feedback resistors.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the M30302GCPGP#35?

The M30302GCPGP#35 achieves a maximum operating frequency of 16 MHz at a supply voltage of 3.0–5.5 V with zero wait states. At 10 MHz, it supports a wider voltage range of 2.7–5.5 V under the same condition. These specifications are confirmed in the "Electric Characteristics" section of the REJ03B0088-0122 datasheet Rev.1.22, and apply specifically to the GP package variant with one-time flash configuration.

Does the M30302GCPGP#35 support external memory expansion, and what bus signals are available?

Yes, the M30302GCPGP#35 supports external memory expansion in microprocessor mode using a 20-bit address bus (A0–A19), 16-bit data bus (D0–D15), and dedicated control signals including CS0–CS3, RD, WR/BHE, WRL/WRH, ALE, HOLD, HLDA, and RDY. These signals are fully documented in Tables 1.6–1.9 and Figure 1.6 of the official datasheet.

How many analog input channels does the M30302GCPGP#35 provide, and what is their resolution?

The M30302GCPGP#35 integrates a single 10-bit successive-approximation A/D converter with 18 total analog input channels: eight dedicated pins (AN0–AN7), eight multiplexed port pins (AN0_0–AN0_7), and two extended inputs (ANEX0, ANEX1). This configuration is explicitly listed in Table 1.1 "Performance Outline" and verified in the "A/D Converter" subsection of the datasheet.

Is the M30302GCPGP#35 pin-compatible with other members of the M16C/30P Group, such as the M30302GDPGP#35?

Yes, the M30302GCPGP#35 is pin-compatible with other 100-pin LQFP variants in the M16C/30P Group, including M30302GDPGP#35 and M30302FAPGP#35. All share identical PLQP0100KB-A package dimensions, pin numbering, and signal mapping per Figures 1.5–1.6 and Tables 1.6–1.9, enabling direct PCB reuse across flash capacity variants.

What are the supported serial communication protocols on the M30302GCPGP#35?

The M30302GCPGP#35 supports UART, clock-synchronous serial I/O, and I²C bus across three configurable serial channels. Channel 0 supports UART/clock-sync/I²C; channels 1 and 2 support UART/clock-sync only. IEBus is not implemented on this variant - only the M16C/30P mask ROM versions (e.g., M30302MAP-XXXGP) list IEBus support per Table 1.1.
