Product details
Overview
M30845FJGP#U5 from Renesas Electronics is a 16/32-bit single-chip microcontroller based on the M32C/80 CPU core, housed in a 100-pin LQFP (PLQP0100KB-A) package. It integrates 512 KB Flash memory, 10-bit A/D converter with 26 channels, CAN 2.0B module, 5-channel serial I/O (including I²C and IEBus), and 4-channel DMAC - targeting industrial control, office automation, and communication equipment.
For engineers reviewing the M30845FJGP#U5 datasheet, M30845FJGP#U5 pinout, M30845FJGP#U5 application, or M30845FJGP#U5 equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases, and two confirmed alternative parts for design continuity and sourcing flexibility.
Technical Context
The M30845FJGP#U5 implements the M32C/80 series CPU core with 108 basic instructions and executes shortest instructions in 31.3 ns at 32 MHz BCLK (VCC1 = 4.2–5.5 V). Its architecture supports single-chip, memory expansion, and microprocessor operation modes across a 16-Mbyte address space.
It features dual-voltage operation (VCC1 = 4.2–5.5 V, VCC2 = 3.0–VCC1), integrated PLL frequency synthesizer, main/sub clock oscillation circuits with external crystal support, and a 15-bit watchdog timer with prescaler - all optimized for deterministic real-time control in temperature-stable environments (–20 to +85°C).

FAQ
What is the maximum operating frequency of the M30845FJGP#U5?
The M30845FJGP#U5 achieves a shortest instruction execution time of 31.3 ns at 32 MHz BCLK when powered at VCC1 = 4.2–5.5 V. At reduced supply (VCC1 = 3.0–5.5 V), it operates up to 24 MHz with 41.7 ns minimum cycle time - validated in Renesas datasheet REJ03B0047-0121.
Does the M30845FJGP#U5 support CAN FD or only classical CAN 2.0B?
The M30845FJGP#U5 supports CAN 2.0B only, as explicitly stated in its datasheet Table 1.1 and block diagram. It does not implement CAN FD protocol features such as variable bit rate or extended data length - confirmed by Renesas' functional specification for the M32C/84 Group.
What package type and dimensions does the M30845FJGP#U5 use?
The M30845FJGP#U5 uses the PLQP0100KB-A 100-pin LQFP package: 14 mm × 14 mm body size, 0.5 mm lead pitch, and standard JEDEC moisture sensitivity level (MSL) 3 - consistent with Renesas' product numbering system where "GP" denotes this specific 100-pin QFP variant.
How many analog input channels does the M30845FJGP#U5's A/D converter support?
The M30845FJGP#U5 integrates a single 10-bit A/D converter supporting 26 analog input channels, as documented in Table 1.2 for the 100-pin package variant - distinct from the 34-channel version offered in the 144-pin M32C/84 models.
Is the M30845FJGP#U5 pin-compatible with other M32C/84 family members?
No - the M30845FJGP#U5 is not pin-compatible with 144-pin M32C/84 variants (e.g., M30845FJGPF#U5). Its 100-pin PLQP0100KB-A footprint differs physically and electrically; pin assignments, I/O count (87 vs. 123), and peripheral mapping (e.g., fewer analog inputs) are package-specific per Renesas' documentation.
