Product details
Overview
UPD78F0588GA-GAM-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KC2-L family, featuring 128 KB on-chip Flash memory, 8 KB RAM, and a 20 MHz max CPU clock. It integrates a 10-bit ADC (8 channels), UART, I²C, and 16-bit timer arrays, targeting embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F0588GA-GAM-AX datasheet, UPD78F0588GA-GAM-AX pinout, UPD78F0588GA-GAM-AX application, or UPD78F0588GA-GAM-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), operating voltage range (2.7–5.5 V), and support for low-power stop modes with wake-up via external interrupt or RTC.
Technical Context
The UPD78F0588GA-GAM-AX implements the 78K0S CPU core with 16-bit address space and 8-bit data path, supporting 131 instructions including bit manipulation and multi-byte arithmetic. Its memory subsystem includes 128 KB Flash with block erase and byte-programmable capability, plus 8 KB SRAM with wait-state configurable access timing.
Peripheral integration centers on real-time control: dual 16-bit timer arrays (each with capture/compare/PWM output), 10-bit ADC with sample-and-hold and hardware-triggered conversion, and serial interfaces (UART0/1, I²C bus interface) with independent clock sources and error detection logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LEAFB#30 | RL78/G13-based; 32 KB Flash, 4 KB RAM, lower power (0.5 µA stop mode), no built-in LIN | Better suited for ultra-low-power battery devices; lacks UART0 LIN compliance and larger Flash capacity | Select when power budget is critical and LIN is not required; requires PCB redesign due to QFN-48 package |
| UPD78F0578GA-GAM-AX | Same KC2-L family; 96 KB Flash, identical peripherals and pinout except reduced Flash size | Direct drop-in replacement where 96 KB Flash suffices; same thermal and electrical behavior | Choose for cost-sensitive designs with smaller firmware footprints; shares same 100-pin LQFP footprint and register map |
Compared with UPD78F0588GA-GAM-AX, R5F100LEAFB#30 offers superior low-power performance but sacrifices LIN support and Flash capacity, while UPD78F0578GA-GAM-AX provides identical peripheral functionality and pin compatibility at reduced memory density-enabling seamless migration within the same PCB layout.

FAQ
What is the maximum operating frequency of the UPD78F0588GA-GAM-AX?
The UPD78F0588GA-GAM-AX supports a maximum CPU clock frequency of 20 MHz when powered at 5.0 V. At 2.7 V, the guaranteed maximum is 10 MHz per Renesas Electrical Specifications (Rev.4.00, Section 27.1). The internal high-speed oscillator and external crystal options (X1/XT1) both scale linearly with supply voltage, and timing-critical peripherals like TAU and UART maintain accuracy within specification across this range. The UPD78F0588GA-GAM-AX does not support dynamic frequency scaling.
Does the UPD78F0588GA-GAM-AX support in-system programming (ISP)?
Yes, the UPD78F0588GA-GAM-AX supports in-system programming via its on-chip bootloader, accessible through UART0 using the Renesas Flash Development Toolkit (FDT). This enables firmware updates without removing the device from the target board. The UPD78F0588GA-GAM-AX requires no external high-voltage programming signals-only standard 3.3 V or 5 V logic-level UART communication-and preserves user RAM during reprogramming. Full Flash sector protection and security lock bits are configurable in software.
How many ADC channels does the UPD78F0588GA-GAM-AX have, and what is their resolution?
The UPD78F0588GA-GAM-AX integrates a single 10-bit successive approximation ADC with 8 analog input channels (AN0–AN7), mapped to P10–P17 and P40–P42. Conversion time is 12.5 µs per sample at 20 MHz CPU clock, and the ADC supports hardware triggers from TAU compare events or external pins. The UPD78F0588GA-GAM-AX also includes dedicated AVREF and AVSS pins to minimize noise coupling into the analog section.
Is the UPD78F0588GA-GAM-AX pin-compatible with other 78K0/KC2-L devices?
The UPD78F0588GA-GAM-AX shares the same 100-pin LQFP package and pin assignment with other 78K0/KC2-L variants including UPD78F0581, UPD78F0582, UPD78F0583, UPD78F0586, UPD78F0587, and UPD78F0578. All share identical peripheral pin mappings, power/ground locations, and reset configuration-making them drop-in replacements where Flash/RAM requirements align. The UPD78F0588GA-GAM-AX differs only in memory size (128 KB Flash), not pin function or timing behavior.
What development tools are officially supported for the UPD78F0588GA-GAM-AX?
Renesas officially supports the UPD78F0588GA-GAM-AX with the QB-MINI2 on-chip debug emulator, RA78K0 assembler (Ver. 4.01), CC78K0 C compiler (Ver. 4.00), and PM+ IDE (Ver. 6.30). Debugging uses the single-wire SWD interface via pins P120–P122. The UPD78F0588GA-GAM-AX is also compatible with the PG-FP5 Flash programmer for mass production programming and the SM+ system simulator for cycle-accurate instruction-level verification before hardware availability.
