Renesas UPD78F0884GA(A2)-GAM-AX

Overview

UPD78F0884GA(A2)-GAM-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/Fx2-L family, featuring 64 KB on-chip Flash memory, 4 KB RAM, and integrated peripherals including 10-bit ADC, UART, I²C, and 16-bit timer arrays. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial sensors and motor drive interfaces.

For engineers reviewing the UPD78F0884GA(A2)-GAM-AX datasheet, UPD78F0884GA(A2)-GAM-AX pinout, UPD78F0884GA(A2)-GAM-AX application, or UPD78F0884GA(A2)-GAM-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), built-in low-voltage detection (LVD), and support for in-circuit debugging via QB-MINI2 emulator - all confirmed for this exact package variant.

Technical Context

The UPD78F0884GA(A2)-GAM-AX implements the 78K0 CPU core with 16-bit address space and supports both ROM-based and RAM-based execution modes. Its clock system integrates three oscillators - external crystal (X1), internal high-speed (16 MHz), and internal low-speed (15 kHz) - with programmable PLL for flexible system timing.

Peripheral integration includes a 10-channel 10-bit ADC with sample-and-hold, two UART channels with LIN support, one I²C interface with SMBus compatibility, and four 16-bit reload timers with input capture/output compare capability - all directly mapped to dedicated SFRs and accessible without external glue logic.

FAQ

What is the maximum operating frequency of the UPD78F0884GA(A2)-GAM-AX?

The UPD78F0884GA(A2)-GAM-AX supports a maximum system clock frequency of 20 MHz. This is achieved using the on-chip PLL with either the external crystal oscillator (X1) or internal high-speed oscillator (16 MHz) as the reference source. The CPU executes instructions at this clock rate, and all peripheral timers operate synchronously unless prescaled.

Does the UPD78F0884GA(A2)-GAM-AX include a hardware watchdog timer?

Yes, the UPD78F0884GA(A2)-GAM-AX includes a dedicated 16-bit hardware watchdog timer (WDT) with its own independent clock source - the internal low-speed oscillator (15 kHz). This ensures reliable timeout detection even if the main system clock fails, and it can be configured to generate either an interrupt or a system reset upon timeout.

Can the UPD78F0884GA(A2)-GAM-AX perform in-system programming of its Flash memory?

Yes, the UPD78F0884GA(A2)-GAM-AX supports full in-system programming (ISP) of its 64 KB on-chip Flash memory via the on-chip bootloader. No external programmer is required - firmware updates can be performed through UART or other serial interfaces using Renesas-provided Flash programming routines and the UPD78F0884GA(A2)-GAM-AX's built-in self-write capability.

What is the ADC resolution and channel count on the UPD78F0884GA(A2)-GAM-AX?

The UPD78F0884GA(A2)-GAM-AX integrates a 10-bit successive approximation ADC with 10 input channels (AN0–AN9), mapped to Port 2 and Port 3 pins. Conversion time is 1.2 μs per sample, and the ADC supports hardware trigger sources including timer overflow and external events - enabling precise synchronized sampling in control loops.

Is the UPD78F0884GA(A2)-GAM-AX pin-compatible with other members of the 78K0/Fx2-L family?

The UPD78F0884GA(A2)-GAM-AX belongs to the 78K0/FB2-L subgroup and shares the same 48-pin LQFP package and pin configuration with other FB2-L devices such as UPD78F0864 and UPD78F0865. However, pin compatibility does not guarantee functional or register-level compatibility - peripheral enable bits, SFR addresses, and default reset states differ between variants and require verification against each device's User's Manual.
