Product details
Overview
M30843FHFP#U5 from Renesas Electronics is a 16/32-bit single-chip microcomputer based on the M32C/80 series CPU core, housed in a 100-pin plastic molded LQFP (PRQP0100JB-A) package. It delivers 31.3 ns shortest instruction execution time at 32 MHz BCLK, integrates a 10-bit A/D converter with 26 channels, dual 8-bit D/A converters, one CAN 2.0B module, and five serial I/O channels - enabling real-time control in automotive body electronics and industrial motor drives.
For engineers reviewing the M30843FHFP#U5 datasheet, M30843FHFP#U5 pinout, M30843FHFP#U5 application, or M30843FHFP#U5 equivalent, this part supports CAN-based distributed control systems, high-precision analog sensing with simultaneous A/D sampling, and deterministic interrupt handling with 38 internal + 8 external sources across seven priority levels - critical for safety-aware embedded firmware development.
Technical Context
The M30843FHFP#U5 implements the M32C/80 CPU architecture with 108 basic instructions and a 16-Mbyte linear address space. Its memory subsystem includes Flash memory (capacity not specified in J-column data but confirmed as Flash variant by 'F' in part number), 128 KB ROM (per product numbering system: 'C' = 128 Kbytes), and RAM capacity consistent with M32C/84 group baseline specifications.
Peripheral integration centers on deterministic real-time operation: Timer A (16-bit × 5 channels) and Timer B (16-bit × 6 channels) support three-phase motor control; Intelligent I/O provides 16-bit time measurement or waveform generation across 8 channels; DMAC II enables chain transfer triggered by any peripheral interrupt source - essential for low-CPU-overhead data movement in sensor fusion or CAN-to-memory buffering.

FAQ
What is the maximum operating frequency and corresponding supply voltage for M30843FHFP#U5?
The M30843FHFP#U5 achieves its shortest instruction execution time of 31.3 ns at 32 MHz BCLK with VCC1 and VCC2 set to 4.2 V–5.5 V. At reduced supply (3.0 V–5.5 V), it operates up to 24 MHz with 41.7 ns minimum instruction time - verified in Table 1.1 and Table 1.2 of the official datasheet REJ03B0047-0121.
Does M30843FHFP#U5 include on-chip Flash memory, and what is its program/erase voltage requirement?
Yes, M30843FHFP#U5 is a Flash memory version (denoted by 'F' in the part number). Its Flash requires either 3.3 V ± 0.3 V or 5.0 V ± 0.5 V for program/erase operations, and supports 100 write/erase cycles across the full memory space per the datasheet specification.
How many analog input channels does the 10-bit A/D converter in M30843FHFP#U5 support?
The M30843FHFP#U5 integrates a single 10-bit A/D converter circuit supporting 26 analog input channels - consistent with the 100-pin package configuration documented in Table 1.2 of the M32C/84 Group datasheet REJ03B0047-0121.
Is M30843FHFP#U5 pin-compatible with other members of the M32C/84 Group, such as the 144-pin variants?
No, M30843FHFP#U5 uses the 100-pin PRQP0100JB-A package and is not pin-compatible with 144-pin variants like M30843FHFP#U5's larger counterparts. Pin assignments differ significantly - e.g., ports P11–P15 and additional analog inputs exist only in the 144-pin version.
What communication interfaces are supported by M30843FHFP#U5 besides CAN?
In addition to its single CAN 2.0B module, M30843FHFP#U5 supports five serial I/O channels implementing clock synchronous serial I/O, clock asynchronous serial I/O (UART), HDLC processing, IEBus, and I²C bus - all confirmed in Tables 1.1 and 1.2 of the official Renesas documentation.
