Renesas M3062LFGPGP#U3C

Overview

M3062LFGPGP#U3C from Renesas Electronics is a 16-bit Flash-based microcontroller in the M16C/62P Group, built on the M16C/60 Series CPU core. It features 256 KB + 4 KB Flash ROM, 20 KB RAM, operates at up to 24 MHz (41.7 ns min instruction time), and integrates dual 16-bit multifunction timers (A/B), 10-bit 26-channel A/D converter, dual 8-bit D/A converters, 2-channel DMAC, I²C, UART, IEBus, and PLL clock synthesis - enabling high-speed control in industrial motor drives and embedded OA equipment.

For engineers reviewing the M3062LFGPGP#U3C datasheet, M3062LFGPGP#U3C pinout, M3062LFGPGP#U3C application, or M3062LFGPGP#U3C equivalent, key selection considerations include its 100-pin LQFP package, -40°C to +85°C operating range, lead-free U3 product code, flash endurance (100× full-chip / 1,000× user ROM / 10,000× block A & 1), and compatibility with memory expansion mode for up to 4 MB address space.

Technical Context

The M3062LFGPGP#U3C implements the M16C/60 Series 16-bit CISC CPU core with 91 basic instructions and supports single-chip, memory expansion, and microprocessor operating modes. Its on-chip system clock generation includes main/subclock circuits with built-in feedback resistors, PLL synthesizer, and on-chip oscillator - enabling flexible clock source selection and re-oscillation detection after main clock stop.

Peripheral integration centers on real-time control: Timer A (16-bit × 5 channels) and Timer B (16-bit × 6 channels) support three-phase motor control; the 26-channel 10-bit A/D converter includes programmable sampling timing; and dual 8-bit D/A outputs provide analog actuation capability. The CCITT-CRC circuit and 15-bit watchdog timer with prescaler enhance system reliability in deterministic embedded applications.

FAQ

What is the maximum operating frequency and corresponding supply voltage range for M3062LFGPGP#U3C?

The M3062LFGPGP#U3C supports a maximum BCLK frequency of 24 MHz at VCC1 = 3.3 V to 5.5 V, achieving a minimum instruction execution time of 41.7 ns. At lower frequencies (e.g., 10 MHz), it operates down to VCC1 = 2.7 V. This dual-voltage flexibility allows use in both 3.3 V and 5 V system designs without level-shifting components.

Does M3062LFGPGP#U3C support in-system programming (ISP) and what are the endurance specifications?

Yes, M3062LFGPGP#U3C supports ISP via on-chip bootloader. Its Flash memory endurance is graded: 100 write/erase cycles for full-chip operations, 1,000 cycles for user ROM area (excluding blocks A and 1), and 10,000 cycles for block A and block 1 - enabling robust firmware updates and parameter storage in field-deployed M3062LFGPGP#U3C units.

What package type and RoHS status does M3062LFGPGP#U3C have?

M3062LFGPGP#U3C uses the 100-pin plastic LQFP package (PLQP0100KB-A) with 0.5 mm pitch. It is lead-free and conforms to RoHS Directive 2011/65/EU, indicated by the "U3" product code in its marking - confirming compliance with environmental regulations for industrial and consumer electronics markets.

How many A/D input channels does M3062LFGPGP#U3C provide, and what is their resolution?

M3062LFGPGP#U3C integrates a single 10-bit successive-approximation A/D converter with up to 26 selectable input channels. All channels share the same 10-bit resolution and reference voltage (AVREF), supporting simultaneous sampling control for multi-sensor applications such as motor current/voltage monitoring and thermal management in M3062LFGPGP#U3C-based systems.

Is IEBus interface hardware-supported on M3062LFGPGP#U3C, and what is its functional scope?

Yes, M3062LFGPGP#U3C includes dedicated hardware IEBus (Inter Equipment Bus) support compliant with NEC's IEBus specification. It handles physical layer timing, frame formatting, and error detection autonomously - enabling direct connection to automotive HVAC controllers, audio head units, and instrument clusters without software bit-banging or external protocol translators.
