Overview
M30302FEPFP#U3 from Renesas Electronics is a 16-bit single-chip microcomputer based on the M16C/60 Series CPU core, operating at up to 16 MHz with 192 KB + 4 KB flash memory and 6 KB RAM in a 100-pin QFP package. It integrates a 10-bit 18-channel A/D converter, dual 16-bit timer groups (Timer A/B), three UART/I²C/IEBus serial interfaces, two DMAC channels, and CCITT-CRC circuitry. It targets real-time control in office equipment, industrial automation, and home appliances.
For engineers reviewing the M30302FEPFP#U3 datasheet, M30302FEPFP#U3 pinout, M30302FEPFP#U3 application, or M30302FEPFP#U3 equivalent, key selection criteria include its 100-pin LQFP package, VCC1=VCC2 supply requirement, -40°C to 85°C operating range, flash endurance of 100 program/erase cycles, and support for single-chip, memory expansion, and microprocessor modes.
Technical Context
The M30302FEPFP#U3 implements the M16C/60 Series 16-bit CISC CPU core with 91 basic instructions and minimum instruction execution time of 62.5 ns at 16 MHz. Its memory architecture supports 1 Mbyte address space with on-chip flash and RAM, and external bus interface with ALE, RD, WR, CS0–CS3, and BYTE control for 8/16-bit data width selection.
Peripheral integration includes three independent serial channels supporting clock-synchronous, UART, I²C Bus (1 channel), and IEBus (1 channel); dual 16-bit timer groups with input capture/output compare capability; and a dedicated 15-bit watchdog timer with prescaler. All timers and serial modules are directly memory-mapped and interrupt-capable with 7 priority levels.

FAQ
What is the maximum operating frequency and corresponding supply voltage for the M30302FEPFP#U3?
The M30302FEPFP#U3 achieves a maximum operating frequency of 16 MHz at VCC1 = VCC2 = 3.0–5.5 V with zero wait states. At 10 MHz, it supports a reduced supply range of 2.7–5.5 V. The device requires identical voltage on both VCC1 and VCC2 pins per Renesas specification.
Does the M30302FEPFP#U3 support in-system programming (ISP) and how many erase/write cycles does its flash memory endure?
Yes, the M30302FEPFP#U3 supports in-system programming via its on-chip debug interface. Its flash memory is rated for 100 program/erase cycles across the entire memory array, as confirmed in the official Renesas documentation (REJ03B0088-0122, Table 1.1).
Which serial communication protocols are natively supported by the M30302FEPFP#U3 and how are they allocated across its three serial channels?
The M30302FEPFP#U3 supports UART, clock-synchronous serial, I²C Bus (on one channel), and IEBus (on one channel). Channel 0 supports UART/clock-sync/I²C; Channels 1 and 2 support UART/clock-sync only. IEBus is implemented exclusively on Channel 0.
What are the analog input capabilities of the M30302FEPFP#U3, including channel count, resolution, and special features?
The M30302FEPFP#U3 integrates a 10-bit A/D converter with 18 total input channels: eight standard (AN0–AN7), eight auxiliary (AN0_0–AN0_7), and two extended inputs (ANEX0, ANEX1). It supports external reference voltage (VREF), internal op-amp connection mode via ANEX0, and hardware-triggered conversion using ADTRG.
Is the M30302FEPFP#U3 pin-compatible with other members of the M16C/30P Group, and what package variant does the "FP" suffix indicate?
Yes, the M30302FEPFP#U3 shares identical pinout and footprint with all M16C/30P Group devices in the PRQP0100JB-A package. The "FP" suffix explicitly denotes the 100-pin plastic QFP (100P6S-A) variant, while "GP" indicates the PLQP0100KB-A (100P6Q-A) variant - both are functionally compatible but mechanically distinct.
