Renesas M30620FCPGP#U7C

Overview

M30620FCPGP#U7C 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 128 KB + 4 KB Flash ROM, 10 KB RAM, 100-pin LQFP package, operates at up to 24 MHz (41.7 ns min instruction time), and integrates dual 16-bit timer groups, 26-channel 10-bit ADC, dual 8-bit DACs, 2-channel DMAC, I²C, UART, IEBus, and PLL clock synthesis - enabling real-time control in industrial motor drives and office equipment.

For engineers reviewing the M30620FCPGP#U7C datasheet, M30620FCPGP#U7C pinout, M30620FCPGP#U7C application, or M30620FCPGP#U7C equivalent, key selection criteria include its -40°C to +85°C operating range, 1,000/10,000-cycle Flash endurance (block A/1), lead-free packaging (U7 code), and compatibility with memory expansion mode for 4 MB address space.

Technical Context

The M30620FCPGP#U7C 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 clock system includes main/subclock generators, on-chip oscillator, and PLL synthesizer - all with built-in feedback resistors - enabling flexible clock source configuration and oscillation stop detection with re-oscillation recovery.

Peripheral integration centers on deterministic real-time control: Timer A (16-bit × 5 channels) and Timer B (16-bit × 6 channels) support three-phase motor control; serial interfaces include 3-channel clock-synchronous/UART/I²C/IEBus; and the CCITT-CRC circuit accelerates data integrity checks in communication stacks.

FAQ

What is the Flash memory endurance specification for M30620FCPGP#U7C?

The M30620FCPGP#U7C has a U7 product code indicating 1,000 program/erase cycles for the user ROM area (excluding Block A and Block 1) and 10,000 cycles for Block A and Block 1. This graded endurance allows frequent firmware updates in designated areas while preserving critical boot code longevity. The specification is validated per Renesas REJ03B0001-0241 Rev.2.41.

Does M30620FCPGP#U7C support memory expansion mode?

Yes, M30620FCPGP#U7C supports memory expansion mode, extending its native 1 MB address space to 4 MB. This capability enables connection to external SRAM, Flash, or peripherals via the multiplexed address/data bus - confirmed in Table 1.1 and Section 1.2 of the M16C/62P Group hardware manual (REJ03B0001-0241).

What is the operating temperature range for M30620FCPGP#U7C?

M30620FCPGP#U7C is rated for -40°C to +85°C operating ambient temperature, consistent with the "Standard" quality grade per Renesas documentation. This range is explicitly defined in Table 1.8 (Product Code) and applies to all U7-coded Flash versions of the M16C/62P Group, including M30620FCPGP#U7C.

Which serial communication protocols does M30620FCPGP#U7C natively support?

M30620FCPGP#U7C natively supports UART, I²C bus, IEBus, and clock-synchronous serial I/O across three configurable channels. Its dedicated IEBus controller and dual clock-sync channels provide hardware-level protocol handling - eliminating bit-banging overhead and ensuring deterministic timing for automotive and industrial bus communication.

Is there an on-chip voltage detection circuit in M30620FCPGP#U7C?

Yes, M30620FCPGP#U7C includes an on-chip voltage detection circuit with programmable reset thresholds (2.6 V to 4.2 V in 0.3 V steps). This feature is documented in Table 1.1 and enables reliable brown-out detection without external supervisor ICs - a key differentiator versus the M16C/62PT variant which omits this function.
