Renesas M30840SGP#U5

Overview

M30840SGP#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 320 KB Flash memory, 10-bit A/D converter with 26 channels, dual 8-bit D/A converters, CAN 2.0B module, and 5-channel serial I/O - enabling real-time control in automotive body electronics and industrial motor drives.

For engineers reviewing the M30840SGP#U5 datasheet, M30840SGP#U5 pinout, M30840SGP#U5 application, or M30840SGP#U5 equivalent, key selection criteria include its 32 MHz max BCLK operation at 4.2–5.5 V, –20 to +85°C industrial temperature range, and support for intelligent I/O waveform generation and three-phase motor control circuits.

Technical Context

The M30840SGP#U5 implements the M32C/80 series CPU core with 108 basic instructions and executes shortest instructions in 31.3 ns at 32 MHz. Its peripheral set includes Timer A (16-bit ×5), Timer B (16-bit ×6), and an 8-channel intelligent I/O unit supporting both time measurement and waveform generation functions.

It features a dedicated CAN 2.0B controller with one channel, CRC-CCITT calculation circuit, X/Y 16×16-bit multiplier, and DMAC II supporting immediate, calculation, and chain transfers activated by all peripheral interrupt sources - optimized for deterministic response in embedded control loops.

FAQ

What is the maximum operating frequency of the M30840SGP#U5?

The M30840SGP#U5 supports a maximum BCLK frequency of 32 MHz, achieving a shortest instruction execution time of 31.3 ns when powered at VCC1 = 4.2–5.5 V. At 24 MHz BCLK, it operates down to 3.0 V supply, delivering 41.7 ns minimum instruction time - verified in Renesas document REJ03B0047-0121, Table 1.2.

Does the M30840SGP#U5 include a CAN controller, and what version does it support?

Yes, the M30840SGP#U5 integrates a single-channel CAN controller compliant with the CAN 2.0B specification, including full ID filtering, message buffering, and error handling. It does not support CAN FD. This functionality is confirmed in Section 1.2 "Performance Overview" and Table 1.2 of the official Renesas datasheet REJ03B0047-0121.

How many analog-to-digital converter channels does the M30840SGP#U5 provide?

The M30840SGP#U5 includes a 10-bit A/D converter with 26 input channels, as specified for the 100-pin package variant in Table 1.2 of Renesas document REJ03B0047-0121. This is fewer than the 34-channel configuration available in the 144-pin M32C/84 variants.

What package type and pin count does the M30840SGP#U5 use?

The M30840SGP#U5 uses the PLQP0100KB-A package: a 100-pin plastic LQFP measuring 14 mm × 14 mm with 0.5 mm lead pitch. This is explicitly defined in the product numbering system (Figure 1.2) and pin assignment diagram (Figure 1.4) of Renesas datasheet REJ03B0047-0121.

Is the M30840SGP#U5 compatible with the M32C/84T high-reliability variant?

No, the M30840SGP#U5 is the standard industrial-grade variant (non-T version), rated for –20°C to +85°C operation. The T version (e.g., M30840TGP#U5) requires matched VCC1/VCC2 supply and supports –40°C to +85°C. These distinctions are documented in Tables 1.1–1.2 and Notes 3–4 of Renesas REJ03B0047-0121.
