Renesas M30876FJAGP#U5

Overview

M30876FJAGP#U5 from Renesas Electronics is a 100-pin LQFP flash-based 16-bit MCU in the M32C/87A family, embedding the M32C/80 CPU core with 512 KB + 4 KB data flash, 31 KB RAM, dual CAN 2.0B channels (1 active), and 10-bit A/D converter across 26 input channels - deployed in industrial motor control and office automation systems requiring deterministic real-time response.

For engineers reviewing the M30876FJAGP#U5 datasheet, M30876FJAGP#U5 pinout, M30876FJAGP#U5 application, or M30876FJAGP#U5 equivalent, key selection criteria include its 100-pin PLQP0100KB-A package, 32 MHz operation at 4.2–5.5 V, integrated 3-phase inverter control timers, on-chip debug support, and CAN 2.0B compliance for automotive-grade communication subsystems.

Technical Context

The M30876FJAGP#U5 implements the M32C/80 CPU core with 108 basic instructions, 16×16→32-bit multiplier, and 16×16+48→48-bit multiply-add capability. It supports single-chip, memory expansion, and microprocessor operating modes with 16-Mbyte external address space and configurable bus interface (8-/16-bit data width, 1–7 wait states).

Its peripheral set includes five 16-bit Timer A units (PWM, encoder input, one-shot), six 16-bit Timer B units (pulse width/period measurement), dedicated 3-phase motor control logic using TA1/TA2/TA4/TB2, two 8-bit D/A converters, and dual UARTs with IrDA, I²C, and HDLC support - all synchronized via four independent clock sources (main, sub, on-chip oscillator, PLL).

FAQ

What is the maximum operating frequency and supply voltage range for the M30876FJAGP#U5?

The M30876FJAGP#U5 operates at up to 32 MHz with VCC1 between 4.2 V and 5.5 V, or at 24 MHz with VCC1 between 3.0 V and 5.5 V. VCC2 must be maintained between 3.0 V and VCC1. These ranges are defined in the REJ03B0127-0151 datasheet Rev.1.51 and validated across the -20°C to +85°C ambient temperature range. The M30876FJAGP#U5 does not support operation outside these specified limits.

Does the M30876FJAGP#U5 include hardware CAN support, and how many channels are active?

Yes, the M30876FJAGP#U5 is an M32C/87A variant and includes one fully functional CAN 2.0B channel with 16 message slots, hardware acceptance filtering, and automatic retransmission. The second CAN channel (CAN1) is physically present but disabled in silicon for this part number - only CAN0 (pins P8_2/P8_3 or P7_6/P7_7) is operational. This is confirmed in Table 1.6 and Note 5 of the datasheet.

What package type and pin count does the M30876FJAGP#U5 use?

The M30876FJAGP#U5 uses a 100-pin LQFP package designated PLQP0100KB-A, with 0.5 mm lead pitch and 14 mm × 14 mm body size. This is explicitly listed in Table 1.6 under "Package Code" and verified in Figure 1.1's product numbering system where "GP" denotes the 100-pin LQFP variant. It is not offered in QFP or 144-pin variants.

How much flash and RAM memory does the M30876FJAGP#U5 provide?

The M30876FJAGP#U5 integrates 512 KB of main flash memory plus an additional 4 KB of dedicated data flash for nonvolatile parameter storage, along with 31 KB of on-chip RAM. These values are specified in Table 1.6 and apply exclusively to the "FJAGP" suffix variant - other members of the M32C/87A family offer different capacities (e.g., 384 KB or 768 KB flash).

Is on-chip debug functionality supported on the M30876FJAGP#U5?

Yes, the M30876FJAGP#U5 supports full on-chip debug via Renesas' E1/E20 emulators using the single-wire debug interface. This includes real-time variable watch, breakpoint setting, and flash programming - documented in Section 1.1.2 and the "Debug functions" row of Table 1.2/1.4. No external debug header is required beyond the standard SWD pins (VCC, GND, SWDIO, SWCLK).
