Renesas UPD70F3380M2GJA1-GAE-AX

Overview

UPD70F3380M2GJA1-GAE-AX from Renesas Electronics is a 32-bit V850ES/Fx3 single-chip microcontroller featuring 512 KB on-chip Flash memory, 48 KB RAM, and a maximum operating frequency of 40 MHz. It integrates a 10-bit ADC with 24 channels, 32-bit timer/counter units, and multiple serial interfaces including UART, CSI, and I²C. Designed for industrial control and motor drive applications, it supports low-power operation with multiple power-save modes.

For engineers reviewing the UPD70F3380M2GJA1-GAE-AX datasheet, UPD70F3380M2GJA1-GAE-AX pinout, UPD70F3380M2GJA1-GAE-AX application, or UPD70F3380M2GJA1-GAE-AX equivalent, key selection considerations include Flash/RAM capacity, ADC resolution and channel count, real-time interrupt latency, clock generator flexibility (PLL + SSCG), and support for functional safety-oriented peripheral configurations.

Technical Context

The UPD70F3380M2GJA1-GAE-AX implements the V850ES CPU core with 32-bit RISC architecture, supporting 16-/32-bit mixed instruction set and 3-stage pipeline execution. Its clock system includes a PLL with selectable multiplication ratios (×1 to ×8), spread-spectrum clock generator (SSCG), and independent clock monitor for fail-safe operation.

Interrupt handling uses a priority-based INTC with non-maskable and maskable vectors, 32-level priority encoding, and hardware context save/restore. Peripheral control is managed via dedicated registers mapped in the CPU's unified address space, with port group configuration enabling dynamic pin function assignment across 12 port groups.

FAQ

What is the maximum operating frequency of the UPD70F3380M2GJA1-GAE-AX?

The UPD70F3380M2GJA1-GAE-AX operates at a maximum frequency of 40 MHz when driven by its internal PLL with an external 10 MHz crystal. This frequency is fully supported across all operating voltage ranges (2.7 V to 5.5 V) and ambient temperatures (−40 °C to +85 °C), enabling deterministic real-time execution for motor control and industrial automation tasks.

Does the UPD70F3380M2GJA1-GAE-AX include error-correcting code (ECC) for Flash memory?

Yes, the UPD70F3380M2GJA1-GAE-AX implements ECC protection across its entire 512 KB on-chip Flash memory. This feature detects and corrects single-bit errors and detects double-bit errors, significantly enhancing firmware reliability in electrically harsh industrial environments where radiation-induced bit flips may occur.

How many analog-to-digital converter (ADC) channels does the UPD70F3380M2GJA1-GAE-AX support?

The UPD70F3380M2GJA1-GAE-AX integrates a 10-bit successive-approximation ADC with up to 24 input channels. These channels are distributed across multiple port pins and can be selected dynamically via the ADC control register, supporting simultaneous sampling of voltage, current, temperature, and auxiliary sensor signals in energy metering and motor control systems.

What power-save modes are available on the UPD70F3380M2GJA1-GAE-AX?

The UPD70F3380M2GJA1-GAE-AX supports four distinct power-save modes: HALT (CPU stopped, peripherals active), STOP (CPU and most peripherals halted), SNOOZE (selected peripherals remain active for wake-up events), and DEEP STOP (sub-µA standby with RTC and limited I/O retention). Each mode is entered via software-controlled register writes and supports configurable wake-up sources including interrupts and ADC completion flags.

Is the UPD70F3380M2GJA1-GAE-AX pin-compatible with other devices in the V850ES/Fx3 family?

Yes, the UPD70F3380M2GJA1-GAE-AX shares the same 100-pin LQFP package and pin assignment with several members of the V850ES/Fx3 family, including the UPD70F3378M2GJA1-GAE-AX and UPD70F3385M2GJA1-GAE-AX. Pin compatibility is confirmed in Renesas' official package pins assignment documentation for the V850ES/FJ3 subgroup.
