Product details

Overview

UPD78F0511AGA-GAM-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KC2 family, featuring 64 KB on-chip flash memory, 4 KB RAM, and a 16-bit timer/counter with PWM output capability. It operates at up to 20 MHz using an external crystal (1–20 MHz) or internal high-speed oscillator (16 MHz), and supports 5V operation with 59 I/O pins in a 64-pin LQFP package. It is used in industrial control panels requiring deterministic real-time response and EEPROM emulation.

For engineers reviewing the UPD78F0511AGA-GAM-AX datasheet, UPD78F0511AGA-GAM-AX pinout, UPD78F0511AGA-GAM-AX application, or UPD78F0511AGA-GAM-AX equivalent, key selection criteria include flash endurance (100,000 write/erase cycles), A/D conversion time (1.2 μs typical), interrupt latency (2–4 CPU cycles), and support for self-programming library Type01 per U18274E.

Technical Context

The UPD78F0511AGA-GAM-AX implements the 78K0 CPU core with 16-bit addressing, supporting 131 instructions including bit manipulation and multi-byte arithmetic. Its peripheral set includes a 10-bit A/D converter with 16 input channels, UART (ch0/ch1), CSI (ch0/ch1), I²C-compatible serial interface, and watchdog timer with independent clock source.

It uses a dual-clock system: main system clock (X1-based or internal high-speed oscillator) and sub-system clock (X2-based or internal low-speed oscillator). Flash memory is organized into 1 KB blocks with individual erase capability, and data retention is guaranteed for 20 years at 85°C per U17516E.

FAQ

What is the maximum operating frequency of the UPD78F0511AGA-GAM-AX?

The UPD78F0511AGA-GAM-AX supports a maximum system clock frequency of 20 MHz. This can be achieved using either an external crystal (1–20 MHz) connected to X1/X2 pins or the internal high-speed oscillator (16 MHz). The instruction cycle time is 50 ns at 20 MHz, enabling deterministic execution for real-time control loops. All timing specifications in the R01UH0008EJ0401 manual assume operation within the rated voltage (4.0–5.5 V) and ambient temperature (−40 to +85°C) ranges.

Does the UPD78F0511AGA-GAM-AX support in-circuit debugging?

Yes, the UPD78F0511AGA-GAM-AX supports in-circuit debugging via the on-chip debug interface compatible with QB-MINI2 and QB-78K0KX2 emulators. Debug features include breakpoint setting, single-step execution, register and memory inspection, and real-time variable watch. The debug interface uses dedicated pins (TCK, TDO, TDI, TMS) and requires no additional firmware overhead. Full debug capabilities are documented in U18371E and U17341E user manuals.

How many A/D input channels does the UPD78F0511AGA-GAM-AX have, and what is their resolution?

The UPD78F0511AGA-GAM-AX integrates a 10-bit successive approximation A/D converter with 16 input channels (AD0–AD15), mapped across ports P0–P4. Conversion time is 1.2 μs typical at 20 MHz system clock. Input voltage range is 0 to V_REF, with V_REF selectable as AVDD or external reference on AVREF pin. Differential input mode is not supported; all channels are single-ended relative to AVSS.

Is the UPD78F0511AGA-GAM-AX pin-compatible with other 78K0/KC2 devices?

Yes, the UPD78F0511AGA-GAM-AX shares the same 64-pin LQFP package and pin assignment with other 78K0/KC2 variants including UPD78F0512AGA-GAM-AX, UPD78F0513AGA-GAM-AX, and UPD78F0514AGA-GAM-AX. Pin compatibility extends to power, reset, clock, and all I/O functions. Differences lie in flash size (64 KB vs. 96 KB), RAM (4 KB vs. 6 KB), and peripheral configuration-enabling drop-in replacement where memory requirements align.

What development tools are officially supported for the UPD78F0511AGA-GAM-AX?

Renesas officially supports RA78K0 assembler (Ver. 4.01), CC78K0 C compiler (Ver. 4.00), ID78K0-QB integrated debugger (Ver. 3.00), and PM+ IDE (Ver. 6.30) for the UPD78F0511AGA-GAM-AX. Programming is performed via PG-FP5 or PG-FP4 flash programmers using the 78K0/Kx2 Flash Memory Programming Application Note (U17739E). All tools are validated against the UPD78F0511AGA-GAM-AX silicon revision and referenced in documents U17199E through U18492E.
