Renesas M30302FEPGP#U5

Overview

M30302FEPGP#U5 from Renesas Electronics is a 16-bit single-chip microcomputer based on the M16C/60 Series CPU core, packaged in a 100-pin LQFP (PLQP0100KB-A), operating at up to 16 MHz with 192 KB + 4 KB flash memory and 6 KB RAM. It integrates a 10-bit 18-channel A/D converter, dual 16-bit timer groups (Timer A/B), three UART/I²C/IEBus serial interfaces, DMAC, CRC circuit, and watchdog timer. It targets industrial control and embedded OA equipment requiring deterministic real-time response.

For engineers reviewing the M30302FEPGP#U5 datasheet, M30302FEPGP#U5 pinout, M30302FEPGP#U5 application, or M30302FEPGP#U5 equivalent, key selection criteria include its 100-pin LQFP package, -20°C to +85°C operating temperature (U5 grade), flash memory programmability, integrated IEBus support, and dual-voltage supply (VCC1=VCC2) requirement.

Technical Context

The M30302FEPGP#U5 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 external bus interface (A0–A19, D0–D15, CS0–CS3, RD/WR/BHE) and internal flash memory organized with Block A (4 KB) for flexible firmware updates.

Peripheral integration includes three independent serial channels supporting clock-synchronous, UART, I²C Bus (1 channel), and IEBus (1 channel); two 16-bit multifunction timer groups (Timer A: 3 channels, Timer B: 3 channels); and a 10-bit A/D converter with 18 analog inputs (AN0–AN7, AN0_0–AN0_7, ANEX0/ANEX1) and external trigger (ADTRG). All timers and serial modules are directly memory-mapped and interrupt-capable.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for the M30302FEPGP#U5?

The M30302FEPGP#U5 achieves a minimum instruction execution time of 62.5 ns at 16 MHz, requiring VCC1 = VCC2 = 3.0–5.5 V. At 10 MHz, it operates down to 2.7 V. The U5 temperature grade specifies –20°C to +85°C operation under these conditions. This ensures reliable high-speed control in industrial environments where voltage tolerance and thermal stability are critical for the M30302FEPGP#U5.

Does the M30302FEPGP#U5 support in-system programming (ISP) and how many program/erase cycles are guaranteed?

Yes, the M30302FEPGP#U5 supports in-system programming via its on-chip debug interface and flash memory controller. Renesas guarantees 100 program/erase cycles across the entire flash array, including the dedicated 4 KB Block A. This endurance rating applies under specified VCC (3.3±0.3 V or 5.0±0.5 V) and temperature conditions, enabling field firmware updates for the M30302FEPGP#U5 throughout its service life.

How does the M30302FEPGP#U5 handle analog-to-digital conversion triggering and channel selection?

The M30302FEPGP#U5 supports both software-triggered and hardware-external A/D conversion via the ADTRG pin (P9_7). It provides 18 analog input sources: eight dedicated AN0–AN7, eight multiplexed AN0_0–AN0_7 on Port 0, and two extended inputs ANEX0/ANEX1. Channel selection is controlled by the ADPC register, allowing sequential or single-channel conversion modes - essential for synchronized sensor acquisition in the M30302FEPGP#U5.

What are the key differences between the FP and GP package variants for the M30302FEPGP#U5?

The M30302FEPGP#U5 uses the GP suffix, indicating the PLQP0100KB-A (100P6Q-A) LQFP package - a 20 mm × 14 mm body with 0.65 mm lead pitch. The FP variant (PRQP0100JB-A, 100P6S-A) has identical pin count and function but differs in land pattern dimensions and thermal characteristics. Pin mapping is fully compatible; however, PCB layout must match the specific footprint for the M30302FEPGP#U5's GP package.

Which serial communication protocols are natively supported by hardware peripherals in the M30302FEPGP#U5?

The M30302FEPGP#U5 integrates three independent serial channels with hardware support for UART, clock-synchronous serial, I²C Bus (1 channel), and IEBus (1 channel). Notably, IEBus is implemented as a dedicated peripheral - not software-emulated - ensuring timing compliance with NEC's automotive audio standard. SDA2/SCL2 and TXD2/RXD2 use open-drain outputs with internal pull-up disable, matching I²C/IEBus electrical requirements for the M30302FEPGP#U5.
