For engineers reviewing the UPD70F3453GF(R)-GAS-AX datasheet, UPD70F3453GF(R)-GAS-AX pinout, UPD70F3453GF(R)-GAS-AX application, or UPD70F3453GF(R)-GAS-AX equivalent, key selection criteria include its V850E CPU core compatibility, 100-pin LQFP package, Flash endurance (100k write/erase cycles), operating voltage range (2.7–5.5 V), and support for standby and real-time clock functions.

Technical Context

The UPD70F3453GF(R)-GAS-AX implements the V850E RISC CPU core with 32-bit data path and Harvard architecture, supporting 16-/32-bit instructions and pipeline execution. It integrates a programmable clock generator with PLL, multiple interrupt sources (including priority-level nesting), and on-chip debug support via MINICUBE-compatible interface.

Peripherals include three independent serial interfaces (UARTA, UARTB, CSIB), dual I²C buses, six 16-bit timer channels (with PWM output capability), and a 10-bit successive-approximation ADC with sample-and-hold. The device supports multiple power-saving modes-wait, stop, and deep-stop-with wake-up via external interrupt or internal timer.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the UPD70F3453GF(R)-GAS-AX?

The UPD70F3453GF(R)-GAS-AX operates at a maximum frequency of 32 MHz when driven by its internal PLL, which accepts an external crystal input between 1 MHz and 20 MHz. This frequency enables sub-microsecond interrupt latency and real-time execution of control algorithms without external clock synthesis components.

Does the UPD70F3453GF(R)-GAS-AX support in-system programming?

Yes, the UPD70F3453GF(R)-GAS-AX supports in-system programming via its on-chip Flash memory using the MINICUBE2 or QB-MINI2 debug emulators. Firmware updates can be performed through UART or dedicated programming pins without removing the UPD70F3453GF(R)-GAS-AX from the target board.

What power-saving modes does the UPD70F3453GF(R)-GAS-AX offer?

The UPD70F3453GF(R)-GAS-AX provides three low-power modes: Wait (CPU halted, peripherals active), Stop (main clock stopped, RAM retained), and Deep-stop (1.2 µA typical, RTC and LVI active). Wake-up is supported via external interrupt, timer match, or LVI event - making the UPD70F3453GF(R)-GAS-AX suitable for battery-backed applications.

Is the UPD70F3453GF(R)-GAS-AX pin-compatible with other V850E/IG3 devices?

The UPD70F3453GF(R)-GAS-AX shares the same 100-pin LQFP package and core pinout with UPD70F3454GF(R)-GAS-AX, but differs in peripheral allocation: UPD70F3454 adds CAN_TX/CAN_RX pins, requiring PCB layout revision. UPD70F3451/3452 (V850E/IF3) use different pin mappings and are not pin-compatible with the UPD70F3453GF(R)-GAS-AX.

What development tools are officially supported for the UPD70F3453GF(R)-GAS-AX?

Renesas officially supports the QB-MINI2 on-chip debugger, PG-FP5 Flash programmer, and CA850 C compiler for the UPD70F3453GF(R)-GAS-AX. Integrated development is enabled via e² studio with V850 plugin, and reference code for UART, ADC, and timer peripherals is provided in Application Notes U18723E–U18732E.
