Renesas M30843FJGP#U3

Overview

M30843FJGP#U3 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 (PLQP0100KB-A) package. It integrates 512 KB Flash memory, 10-bit A/D converter with 26 channels, CAN 2.0B module, and dual 8-bit D/A converters - enabling real-time motor control and industrial communication in office equipment and automotive ECUs.

For engineers reviewing the M30843FJGP#U3 datasheet, M30843FJGP#U3 pinout, M30843FJGP#U3 application, or M30843FJGP#U3 equivalent, key selection criteria include its 32 MHz max BCLK operation at 4.2–5.5 V, 144 I/O capability (in 144-pin variants), and integrated intelligent I/O for waveform generation and time measurement - critical for deterministic timing in embedded motion control systems.

Technical Context

The M30843FJGP#U3 implements the M32C/80 CPU core with 108 basic instructions and executes shortest instructions in 31.3 ns at 32 MHz. Its architecture includes four independent clock generation circuits (main/sub oscillators, on-chip oscillator, PLL), supporting flexible system clocking and fail-safe main clock stop detection.

It features a 16-Mbyte address space, four-channel DMAC with immediate/calculation/chain transfer modes, CRC-CCITT calculation circuit, and X/Y converter (16×16 bits). Peripheral integration includes five serial I/O channels (UART, clock-synchronous/asynchronous, IEBus, I²C), Timer A (5×16-bit) and Timer B (6×16-bit), and three-phase motor control logic.

FAQ

What is the maximum operating frequency of the M30843FJGP#U3?

The M30843FJGP#U3 supports a maximum BCLK frequency of 32 MHz when operated at VCC1 = 4.2 V to 5.5 V. At lower supply voltages (3.0 V to 5.5 V), the maximum BCLK is reduced to 24 MHz. The shortest instruction execution time is 31.3 ns at 32 MHz, confirming hard real-time capability for industrial control loops. This specification is validated in Table 1.1 of the official Renesas REJ03B0047-0121 datasheet.

Does the M30843FJGP#U3 include an integrated CAN controller?

Yes, the M30843FJGP#U3 includes one fully compliant CAN 2.0B module with message object buffers and error handling logic. It supports standard and extended identifiers, bit rates up to 1 Mbps, and automatic retransmission. The CAN interface uses dedicated pins P82 (CAN0OUT) and P83 (CAN0IN), requiring only an external physical-layer transceiver. This functionality is confirmed in Section 1.2 and Table 1.1 of the M32C/84 Group datasheet.

What is the Flash memory endurance rating for the M30843FJGP#U3?

The M30843FJGP#U3 Flash memory is rated for 100 program/erase cycles across the entire memory space. Programming and erasure require either 3.3 V ±0.3 V or 5.0 V ±0.5 V supply, and the endurance value reflects guaranteed minimum cycles under specified voltage and temperature conditions. This specification appears in Table 1.1 under "Flash Memory" characteristics and applies specifically to the F-series Flash variant like M30843FJGP#U3.

Which package type does the M30843FJGP#U3 use?

The M30843FJGP#U3 uses the PLQP0100KB-A package: a 100-pin plastic LQFP with 14 mm × 14 mm body size and 0.5 mm lead pitch. This is explicitly defined in Figure 1.2 (Product Numbering System) and confirmed in Table 1.3 and Figure 1.4 (Pin Assignment for 100-Pin Package) of the Renesas M32C/84 Group datasheet REJ03B0047-0121.

What analog input capabilities does the M30843FJGP#U3 provide?

The M30843FJGP#U3 integrates a 10-bit successive-approximation A/D converter with 26 input channels, supporting single-ended and differential conversions. Input voltage range is AVss to AVcc (typically 0–5 V), and conversion time is 1.2 µs per sample. These 26 channels map to dedicated analog pins (e.g., AN00–AN07, AN20–AN27, KI0–KI3) and are documented in Figures 1.4 and 1.5 and Table 1.2 of the official datasheet.
