Product details
Overview
M30855FHGP#U3 from Renesas Electronics is a 16/32-bit single-chip microcontroller based on the M32C/80 series CPU core, housed in a 100-pin plastic molded LQFP (PLQP0100KB-A) package. It delivers 31.3 ns minimum instruction execution time at 32 MHz BCLK, integrates dual CAN 2.0B modules, a 10-bit 26-channel A/D converter, and 4-channel DMAC - targeting industrial motor control and automotive body electronics.
For engineers reviewing the M30855FHGP#U3 datasheet, M30855FHGP#U3 pinout, M30855FHGP#U3 application, or M30855FHGP#U3 equivalent, key selection criteria include its 100-pin LQFP footprint, dual-CAN interface with wake-up capability, 26-channel analog input support, and −40 to +85°C operating range for harsh-environment embedded control.
Technical Context
The M30855FHGP#U3 implements the M32C/80 CPU core with 108 basic instructions and supports single-chip, memory expansion, and microprocessor operating modes. Its clock system includes main/sub crystal oscillators, on-chip oscillator, and PLL frequency synthesizer - all with built-in feedback resistors requiring external ceramic resonators or crystals.
Peripheral integration includes Timer A (16-bit × 5 channels) and Timer B (16-bit × 6 channels), intelligent I/O with time measurement/waveform generation (16-bit × 8 channels), five serial I/O channels (UART, clock-synchronous/asynchronous, IEBus, I²C), and a CRC-CCITT calculation circuit. The device uses separate VCC1 (4.2–5.5 V) and VCC2 (3.0–VCC1) supply domains.

FAQ
What is the maximum operating frequency of the M30855FHGP#U3?
The M30855FHGP#U3 achieves a minimum instruction execution time of 31.3 ns at 32 MHz BCLK under VCC1 = 4.2–5.5 V conditions. Its PLL frequency synthesizer allows flexible clock scaling, but the maximum guaranteed BCLK remains 32 MHz per the official datasheet specification for the M32C/85 Group. This frequency enables deterministic real-time response in motor control loops and CAN message handling within the M30855FHGP#U3.
Does the M30855FHGP#U3 support CAN FD or only classical CAN 2.0B?
The M30855FHGP#U3 supports only CAN 2.0B - not CAN FD. Its two CAN modules comply fully with ISO 11898-1:2003 and support standard and extended identifiers, message filtering, and wake-up functionality (CAN1WU). CAN FD features such as variable bit rate and extended data length are absent in the M32C/85 architecture. For CAN FD requirements, designers should consider newer families like RX72M or RA6T2, not the M30855FHGP#U3.
What is the flash endurance rating for the M30855FHGP#U3?
The M30855FHGP#U3 flash memory is rated for 100 program/erase cycles across the entire memory space, as specified in the Renesas M32C/85 Group datasheet (REJ03B0046-0121, Rev.1.21). This applies to both 3.3 V ± 0.3 V and 5.0 V ± 0.5 V programming voltages. Field firmware updates must account for this limited endurance - wear leveling or external storage is recommended for frequent reprogramming scenarios involving the M30855FHGP#U3.
How many analog input channels does the M30855FHGP#U3 support?
The M30855FHGP#U3 supports 26 analog input channels for its 10-bit A/D converter, consistent with the 100-pin package variant of the M32C/85 Group. These channels map to pins P00–P07 (AN0–AN7), P100–P107 (AN0–AN7 again, shared with KI0–KI3), P150–P157 (AN150–AN157), and P101–P104 (AN1–AN4). No external analog multiplexer is required to access all 26 channels, and they are usable simultaneously under DMA control in the M30855FHGP#U3.
Is the M30855FHGP#U3 pin-compatible with other M32C/85 variants?
Yes - the M30855FHGP#U3 shares identical pinout and footprint with all 100-pin LQFP variants in the M32C/85 Group, including M30855FJGP#U3 and M30855FHGP#U3T. Differences between these variants lie solely in ROM type (Flash vs. mask), capacity (512 KB), and temperature grade (standard vs. −40°C to +85°C). The PLQP0100KB-A package and signal mapping remain unchanged, enabling direct substitution within the same package family for the M30855FHGP#U3.
