Renesas M30262F6GP#HU7

Overview

M30262F6GP#HU7 from Renesas Electronics is a 16-bit single-chip microcomputer in the M16C/26 group, featuring a M16C/60 Series CPU core, 48 KB + 4 KB Flash ROM, 2 KB RAM, and operation up to 20 MHz at 3.0–5.5 V. It integrates five 16-bit Timer A channels, three 16-bit Timer B channels, a three-phase motor control timer, 10-bit 8-channel A/D converter, two UARTs, one I²C-capable UART, and dual-channel DMAC-making it suitable for industrial motor control and office equipment subsystems.

For engineers reviewing the M30262F6GP#HU7 datasheet, M30262F6GP#HU7 pinout, M30262F6GP#HU7 application, or M30262F6GP#HU7 equivalent, key selection considerations include its 48-pin QFP package, -40°C to +85°C operating temperature, 1000-program/10000-erase endurance in data area, on-chip oscillator with main/sub-clock support, and I/O withstand voltage of 5.0 V.

Technical Context

The M30262F6GP#HU7 implements a silicon-gate CMOS M16C/60 Series CPU core with 91 basic instructions and 50 ns minimum instruction execution time at 20 MHz. Its memory map spans 1 MB (00000h–FFFFFh), with Flash ROM allocated top-down and RAM bottom-up, plus dedicated SFR space (00000h–003FFh) and interrupt vector tables at fixed addresses.

Peripheral integration includes three independent clock generation circuits (main, sub, on-chip oscillator), hardware-based three-phase motor control logic synchronized to Timer A/B outputs, and flexible serial interface routing-UART2 supports UART, clock-synchronous serial, I²C bus, or IEBus modes via software configuration without external components.

FAQ

What is the maximum operating frequency and supply voltage range for the M30262F6GP#HU7?

The M30262F6GP#HU7 operates at up to 20 MHz when supplied with 3.0–5.5 V, and supports 10 MHz operation down to 2.7 V. Its shortest instruction execution time is 50 ns at 20 MHz and 3.0 V. The device uses separate analog (AVCC/AVSS) and digital (VCC/VSS) power domains to minimize noise coupling into the 10-bit A/D converter.

Does the M30262F6GP#HU7 support I²C communication, and how is it implemented?

Yes, the M30262F6GP#HU7 supports I²C communication via UART2 pins P70 (SDA) and P71 (SCL), which are N-channel open-drain outputs requiring external pull-up resistors. This function is enabled by configuring the serial mode control register (SMR2) and selecting I²C bus mode-not a dedicated hardware I²C peripheral, but fully compliant with standard I²C protocol timing requirements.

What is the purpose of the three-phase motor control timer in the M30262F6GP#HU7?

The three-phase motor control timer in the M30262F6GP#HU7 is a dedicated hardware block that generates six complementary PWM outputs with programmable dead-time insertion, fault input monitoring (e.g., overcurrent), and automatic shutdown. It directly drives external gate drivers for BLDC or induction motor inverters without CPU intervention, ensuring precise timing and safety-critical responsiveness.

How many A/D converter channels does the M30262F6GP#HU7 have, and what is their resolution?

The M30262F6GP#HU7 features an integrated 10-bit successive-approximation A/D converter with eight input channels (AN0–AN7), mapped to port P100–P107. Conversion is triggered by software, timer, or external signal (P15/ADtrg), and results are stored in dedicated 16-bit result registers with optional left/right justification for direct DSP processing.

What does the "U7" suffix in M30262F6GP#HU7 indicate?

Per Renesas product coding (Table 1.3), the "U7" suffix in M30262F6GP#HU7 specifies the extended temperature grade (-40°C to +85°C) and 10,000 erase cycles in the Flash data area. It also denotes lead-free packaging compliant with RoHS Directive, distinguishing it from "D7" (same temp grade, leaded) and "U3" (0°C to +60°C, 10,000 erase cycles).
