Renesas M3062LFGPFP#U5C

Overview

M3062LFGPFP#U5C from Renesas Electronics is a 16-bit Flash microcontroller in the M16C/62P Group, built on a silicon-gate CMOS process with an M16C/60 Series CPU core. It features 256 KB + 4 KB Flash ROM, 20 KB RAM, 100-pin LQFP package, and operates at up to 24 MHz (41.7 ns min instruction time) across −20°C to +85°C ambient temperature. It targets industrial control systems requiring integrated motor control, analog sensing, and serial communication.

For engineers reviewing the M3062LFGPFP#U5C datasheet, M3062LFGPFP#U5C pinout, M3062LFGPFP#U5C application, or M3062LFGPFP#U5C equivalent, key selection criteria include its 10-bit 26-channel A/D converter, dual 8-bit D/A outputs, three-phase motor control circuit, IEBus and I²C interfaces, and 2-channel DMAC for deterministic real-time embedded control.

Technical Context

The M3062LFGPFP#U5C implements a single-chip 16-bit architecture with a 1 MB address space expandable to 4 MB, supporting single-chip and memory expansion modes. Its peripheral set includes Timer A (16-bit × 5 channels), Timer B (16-bit × 6 channels), and a dedicated three-phase motor control circuit for brushless DC drive.

It integrates four clock generation circuits - main clock, subclock, on-chip oscillator, and PLL synthesizer - with built-in feedback resistors and oscillation stop detection. The device supports multiple serial protocols: three channels of clock-synchronous/UART/I²C/IEBus and two additional clock-synchronous-only channels.

FAQ

What is the maximum operating frequency and corresponding instruction execution time for M3062LFGPFP#U5C?

The M3062LFGPFP#U5C supports a maximum BCLK frequency of 24 MHz, achieving a minimum instruction execution time of 41.7 ns under VCC1 = 3.3–5.5 V conditions. This timing is confirmed in Table 1.1 of the M16C/62P Group hardware manual (Rev. 2.41). The device also supports 10 MHz operation down to 2.7 V for low-voltage applications.

Does M3062LFGPFP#U5C include hardware support for IEBus communication?

Yes, M3062LFGPFP#U5C integrates native IEBus physical layer support within its serial interface modules, as documented in Tables 1.1–1.3 and Figure 1.1. It requires only external passive components (resistors/capacitors) to implement full IEBus node functionality - no external transceiver IC is needed for standard automotive body network implementations.

What are the Flash memory endurance specifications for M3062LFGPFP#U5C?

M3062LFGPFP#U5C uses a graded Flash architecture: Block A and Block 1 support 10,000 program/erase cycles, while the remaining user ROM area is rated for 1,000 cycles. This is specified in Table 1.8 (Product Code U5) and applies to the −20°C to +85°C operating range. The device accepts 3.3±0.3 V or 5.0±0.5 V programming voltage.

Which package type and footprint does M3062LFGPFP#U5C use?

M3062LFGPFP#U5C is packaged in a 100-pin plastic LQFP (PLQP0100KB-A), equivalent to the industry-standard 100P6Q-A footprint: 14 mm × 14 mm body size, 0.5 mm lead pitch, and RoHS-compliant lead-free finish. This matches the GP suffix in the part number and is confirmed in Table 1.5 and Figure 1.3.

Can M3062LFGPFP#U5C operate in single-chip mode without external memory?

Yes, M3062LFGPFP#U5C operates in single-chip mode by default, with all program and data memory integrated on-die (256 KB + 4 KB Flash, 20 KB RAM). External memory expansion is optional and enabled only when configured for memory expansion mode - no external ROM or RAM is required for basic operation.
