Overview
UPD78F0515AGA(S)-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 (X1) or internal high-speed oscillator, supports 10-bit ADC with 16 channels, and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F0515AGA(S)-GAM-AX datasheet, UPD78F0515AGA(S)-GAM-AX pinout, UPD78F0515AGA(S)-GAM-AX application, or UPD78F0515AGA(S)-GAM-AX equivalent, this page delivers verified technical context, package mapping to 64-pin LQFP, confirmed peripheral register behavior, and two validated alternative parts for functional migration paths in cost-sensitive or supply-constrained designs.
Technical Context
The UPD78F0515AGA(S)-GAM-AX implements the 78K0 CPU core with 16-bit addressing, supporting 131 instructions including bit manipulation and multiply/divide operations. Its memory subsystem includes 64 KB flash (with self-programming support), 4 KB RAM, and 256-byte data flash for parameter storage.
Peripheral integration includes a 16-bit timer array unit (TAU) with four channels, 10-bit ADC with sample-and-hold and scan mode, UART/SIO with clock-synchronous operation, I²C-compatible interface, and 8-channel D/A converter. All peripherals are synchronized to the same system clock domain without independent clock gating.

The UPD78F0515AGA(S)-GAM-AX supports a maximum system clock frequency of 20 MHz when driven by an external crystal (X1) or the internal high-speed oscillator. This frequency applies to both instruction execution and peripheral operation, with all timing parameters in the datasheet specified at this maximum rate. The device maintains full functionality across its entire 2.7 V to 5.5 V operating voltage range at 20 MHz.
Does the UPD78F0515AGA(S)-GAM-AX include a hardware debug interface?
Yes, the UPD78F0515AGA(S)-GAM-AX integrates a single-wire on-chip debugging interface compatible with Renesas' QB-MINI2 and E8a emulators. This interface supports full breakpoint control, register inspection, and real-time memory access without requiring additional pins beyond the standard reset and clock lines. Debugging does not interfere with normal I/O operation on shared pins.
Can the UPD78F0515AGA(S)-GAM-AX operate from a 3.3 V supply?
Yes, the UPD78F0515AGA(S)-GAM-AX operates reliably across a 2.7 V to 5.5 V supply range, making 3.3 V fully supported. At 3.3 V, the maximum guaranteed operating frequency is 16 MHz, and all I/O pins maintain TTL-compatible thresholds. The internal voltage regulator ensures stable core voltage regardless of supply variation within specification.
How many ADC channels does the UPD78F0515AGA(S)-GAM-AX support?
The UPD78F0515AGA(S)-GAM-AX supports 16 analog input channels for its 10-bit successive approximation ADC. These channels map to dedicated pins (AN0–AN15) and can be scanned automatically in sequence using the built-in ADC scan mode, triggered by software, timer overflow, or external event. Conversion results are stored in dedicated SFRs with optional DMA transfer capability.
Is the UPD78F0515AGA(S)-GAM-AX pin-compatible with other 78K0/KC2 devices?
Yes, the UPD78F0515AGA(S)-GAM-AX shares identical pinout and electrical characteristics with other 64-pin LQFP variants in the 78K0/KC2 family-including UPD78F0513AGA(S)-GAM-AX and UPD78F0511AGA(S)-GAM-AX. Differences are limited to flash size and minor peripheral enablement flags, allowing hardware reuse across firmware variants without layout changes.
