Renesas M30873FHAGP#U3

Overview

M30873FHAGP#U3 from Renesas Electronics is a 32-bit M32C/80-core microcontroller in the M32C/87A family, housed in a 100-pin LQFP (PLQP0100KB-A) package. It integrates 384 KB flash ROM + 4 KB data flash, 24 KB RAM, dual 10-bit ADC (26 channels in single-chip mode), two 8-bit DACs, two UARTs with IrDA support, and one CAN 2.0B channel - targeting industrial motor control and embedded communication devices.

For engineers reviewing the M30873FHAGP#U3 datasheet, M30873FHAGP#U3 pinout, M30873FHAGP#U3 application, or M30873FHAGP#U3 equivalent, key selection criteria include its 24 MHz/32 MHz dual-frequency operation, CAN 2.0B compliance with 16-slot message buffer, on-chip dead-time timer for 3-phase inverter control, and -40°C to +85°C extended temperature grade option.

Technical Context

The M30873FHAGP#U3 implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit, 16×16+48→48-bit). Its external bus interface supports 16-Mbyte address space, 4 chip selects, and configurable 8-/16-bit data width with 1–7 wait states - enabling memory expansion for real-time control firmware.

It features dual DMA controllers (DMAC and DMACII), 70 interrupt vectors with 7 priority levels, and integrated peripherals including Timer A (5×16-bit) and Timer B (6×16-bit) supporting PWM, encoder input, pulse width/period measurement, and dedicated 3-phase motor control using TA1–TA4 and TB2.

FAQ

What is the maximum operating frequency of the M30873FHAGP#U3 and under what voltage conditions?

The M30873FHAGP#U3 operates at up to 32 MHz when supplied with VCC1 = 4.2 V to 5.5 V, and at up to 24 MHz across VCC1 = 3.0 V to 5.5 V. These ratings are specified in the official Renesas REJ03B0127-0151 datasheet, and the M30873FHAGP#U3 must be configured with appropriate PLL settings and clock dividers to meet timing requirements at each voltage range.

Does the M30873FHAGP#U3 include an integrated CAN controller, and how many channels does it support?

Yes, the M30873FHAGP#U3 includes one CAN 2.0B-compliant controller (M32C/87A variant), supporting 16 message slots per channel. Unlike the M32C/87 (dual CAN) or M32C/87B (no CAN), the M30873FHAGP#U3 provides exactly one CAN channel - confirmed in Table 1.5 and Figure 1.1 of the Renesas datasheet - making it suitable for single-bus industrial networks.

What package type and pin count does the M30873FHAGP#U3 use, and is it RoHS compliant?

The M30873FHAGP#U3 uses a 100-pin LQFP package (PLQP0100KB-A), 14 mm × 14 mm body with 0.5 mm pitch. Per Renesas documentation and environmental notices in REJ03B0127-0151, the M30873FHAGP#U3 complies with EU RoHS Directive requirements, and lead-free assembly is supported. The "#U3" suffix denotes tape-and-reel packaging with moisture sensitivity level (MSL) 3.

How many analog-to-digital converter (ADC) channels are available on the M30873FHAGP#U3, and what is their resolution?

The M30873FHAGP#U3 features a 10-bit successive-approximation ADC with 26 input channels in single-chip mode (reduced to 10 channels in memory expansion or microprocessor modes). All channels include sample-and-hold functionality, and conversion time is ≤1.5 μs - verified in Tables 1.3 and 1.4 of the Renesas datasheet for the 100-pin M32C/87A configuration.

What debug and programming interfaces are supported by the M30873FHAGP#U3?

The M30873FHAGP#U3 supports on-chip debug via the dedicated debug interface (using pins P6_0–P6_3 and RESET), enabling full JTAG-style breakpoints, register inspection, and flash reprogramming in-system. It also supports ROM code protection and ID code verification to prevent unauthorized access - all documented in Section 1.1.2 and Table 1.4 of the Renesas REJ03B0127-0151 specification for M32C/87A devices.
