Renesas M30833FJFP#U3

Overview

M30833FJFP#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 (PRQP0100JB-A) package. It delivers 31.3 ns minimum instruction execution time at 32 MHz, integrates a 10-bit dual A/D converter (26 channels), CAN 2.0B module, 5-channel serial I/O, and 4-channel DMAC - targeting industrial motor control, office automation, and embedded communications equipment.

For engineers reviewing the M30833FJFP#U3 datasheet, M30833FJFP#U3 pinout, M30833FJFP#U3 application, or M30833FJFP#U3 equivalent, key selection criteria include its 100-pin LQFP footprint, CAN 2.0B compliance, 26-channel 10-bit ADC, 32 MHz operation at 4.2–5.5 V, and support for IEBus, I²C, and HDLC protocols in resource-constrained real-time control systems.

Technical Context

The M30833FJFP#U3 implements the M32C/80 CPU core with 108 basic instructions and a 16-Mbyte address space. Its peripheral set includes Timer A (5×16-bit) and Timer B (6×16-bit), intelligent I/O with 5 time-measurement and 10 waveform-generation channels, and a three-phase motor control circuit.

It features four clock generation circuits - main/sub crystal oscillators, on-chip oscillator, and PLL frequency synthesizer - with built-in feedback resistors requiring external crystal or ceramic resonator. The CAN module supports full CAN 2.0B protocol with message objects and error handling, and the DMAC II supports immediate, calculation, and chain transfer modes triggered by any peripheral interrupt source.

FAQ

What is the maximum operating frequency of the M30833FJFP#U3 and under what voltage conditions?

The M30833FJFP#U3 achieves a maximum operating frequency of 32 MHz (BCLK) when supplied with 4.2 V to 5.5 V. At lower voltages (3.0–3.6 V), the maximum frequency is reduced to 20 MHz. This dual-voltage/frequency scaling allows design flexibility for power-constrained applications while maintaining real-time performance where needed. The M30833FJFP#U3 datasheet specifies these limits in Table 1.2 under Electrical Characteristics.

Does the M30833FJFP#U3 support CAN FD or only classical CAN 2.0B?

The M30833FJFP#U3 supports only CAN 2.0B specification, not CAN FD. Its CAN module implements standard 11-bit and 29-bit identifier frames with hardware message objects, acceptance filtering, and error confinement - but lacks the variable bit rate, extended data length, and CRC enhancements of CAN FD. For CAN FD requirements, designers must consider newer Renesas RX or RA family devices. The M30833FJFP#U3 documentation explicitly states "Supporting CAN 2.0B specification" in Section 1.2.

How many analog input channels does the M30833FJFP#U3 have, and are they shared with digital I/O?

The M30833FJFP#U3 includes 26 dedicated analog input channels for its dual 10-bit A/D converter, mapped across ports P0, P1, P2, P10, and P100–P107. These pins are multiplexed: each analog input (e.g., AN00–AN07 on P00–P07) functions as a digital I/O when the ADC is disabled or configured for alternate use. Pin assignment details are confirmed in Figure 1.4 and Table 1.4 of the M30833FJFP#U3 datasheet.

What package type and pin count does the M30833FJFP#U3 use?

The M30833FJFP#U3 uses a 100-pin plastic molded LQFP package designated PRQP0100JB-A (100P6S-A), with 0.5 mm lead pitch and 14 mm × 14 mm body size. This is distinct from the 144-pin variant (PLQP0144KA-A) used by other M32C/83 family members. The package type is unambiguously indicated in the part number suffix "FP" and confirmed in Table 1.3 and Figure 1.4 of the M30833FJFP#U3 datasheet.

Is the M30833FJFP#U3 supported by modern IDEs and debug tools?

Yes, the M30833FJFP#U3 is supported by Renesas' legacy CS+ (formerly High-performance Embedded Workshop) IDE with E1/E20 debug emulators. While not natively supported in newer e2 studio (which targets RX/RA families), CS+ remains actively maintained for M32C/83 legacy development. Renesas provides full peripheral register definitions, startup code, and example projects for the M30833FJFP#U3 in its official documentation suite.
