Renesas M30873FHAGP#U5

Overview

M30873FHAGP#U5 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, CAN 2.0B (1-channel), and advanced motor control timers - targeting industrial automation and embedded motion control systems.

For engineers reviewing the M30873FHAGP#U5 datasheet, M30873FHAGP#U5 pinout, M30873FHAGP#U5 application, or M30873FHAGP#U5 equivalent, key selection considerations include its 24 MHz/32 MHz dual-frequency operation, CAN 2.0B compliance with 16-slot message buffer, integrated 3-phase inverter control logic, low-power stop mode (0.8 μA), and 100-pin LQFP footprint with mixed-signal I/O routing.

Technical Context

The M30873FHAGP#U5 implements the M32C/80 CPU core with 108 basic instructions and hardware multiplier (16×16→32-bit). Its memory subsystem supports 16-Mbyte external address space with configurable bus width (8/16-bit), up to 7 wait states, and four chip selects - enabling direct interface to SRAM, Flash, or peripherals without glue logic.

Peripheral integration includes DMAC (4 channels, cycle-steal), DMACII (burst/chain transfer), five 16-bit Timer A units (PWM, encoder input), six 16-bit Timer B units (pulse width/period measurement), and on-chip dead-time generation for 3-phase motor control - all synchronized via shared clock domains and interrupt vectors (70 total, 7 priority levels).

FAQ

What is the maximum operating frequency and corresponding voltage range for M30873FHAGP#U5?

The M30873FHAGP#U5 operates at up to 32 MHz with VCC1 = 4.2–5.5 V, or 24 MHz with VCC1 = 3.0–5.5 V. VCC2 must be within 3.0 V to VCC1. These ranges are validated per Renesas specification REJ03B0127-0151 Rev.1.51, ensuring reliable instruction execution and peripheral timing at rated speeds. The M30873FHAGP#U5 does not support 32 MHz operation below 4.2 V.

Does M30873FHAGP#U5 support CAN FD or only classical CAN 2.0B?

M30873FHAGP#U5 supports only CAN 2.0B (ISO 11898-1:2003), not CAN FD. It implements one CAN channel (CAN0) with 16 message slots, bit rates up to 1 Mbps, and full error confinement. CAN FD features such as flexible data-rate and extended payload are absent - confirmed in Tables 1.1–1.4 and Figure 1.2 of the official datasheet. The M30873FHAGP#U5 remains compatible with legacy CAN networks but requires external gateway for CAN FD interoperability.

How many ADC channels are available in single-chip mode for M30873FHAGP#U5?

In single-chip mode, the M30873FHAGP#U5 provides 26 channels of 10-bit ADC with sample-and-hold functionality. This is explicitly specified in Table 1.4 (100-pin package) of REJ03B0127-0151 Rev.1.51. Channel count drops to 10 in memory expansion or microprocessor modes. All 26 channels are accessible via dedicated ANx_y pin names and support simultaneous sampling triggers from timers or software.

What debug interfaces are supported by M30873FHAGP#U5?

M30873FHAGP#U5 supports on-chip debug via the standard Renesas E8/E8a debug interface, enabling full JTAG-based debugging, flash programming, and real-time trace. It includes ROM code protection and ID code check for secure firmware deployment. No SWD or ARM-style debug is supported - the M30873FHAGP#U5 debug architecture is proprietary to the M32C family and requires Renesas-compatible tools like the E8 emulator or Flash Development Toolkit.

Is the 100-pin LQFP package of M30873FHAGP#U5 RoHS-compliant?

Yes, the M30873FHAGP#U5 in PLQP0100KB-A package is RoHS-compliant per EU Directive 2011/65/EU, as confirmed in Renesas environmental documentation and product change notices. Lead-free matte tin plating is applied to all I/O terminals, and halogen-free molding compound is used. Compliance applies to both standard (-20°C to +85°C) and optional extended (-40°C to +85°C) temperature grades of the M30873FHAGP#U5.
