Product details
Overview
UPD78F0515AGAA2-GAM-G 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 A/D conversion across 16 channels, and targets embedded control in industrial sensors and motor drive interfaces.
For engineers reviewing the UPD78F0515AGAA2-GAM-G datasheet, UPD78F0515AGAA2-GAM-G pinout, UPD78F0515AGAA2-GAM-G application, or UPD78F0515AGAA2-GAM-G equivalent, key selection criteria include flash endurance (100,000 write/erase cycles), A/D conversion time (1.2 μs typical), operating voltage range (2.7–5.5 V), and support for I²C, UART, and CSI serial interfaces in a 64-pin LQFP package.
Technical Context
The UPD78F0515AGAA2-GAM-G implements the 78K0 CPU core with 16-bit addressing, supporting 131 instructions including bit manipulation and multiply/divide operations. It integrates a 16-bit watchdog timer, power-on reset circuitry, and low-voltage detection with interrupt capability.
Its peripheral set includes three 16-bit timer/counters (one with input capture/output compare), one 8-bit reload timer, a 10-bit A/D converter with sample-and-hold, and serial interfaces: one I²C bus interface, two UART channels, and one CSI interface - all configurable via dedicated SFRs and interrupt vectors.

FAQ
What is the maximum operating frequency of the UPD78F0515AGAA2-GAM-G?
The UPD78F0515AGAA2-GAM-G supports a maximum system clock frequency of 20 MHz when driven by an external crystal connected to X1/X2 pins. Internal high-speed oscillator operation is also supported at 20 MHz, with factory-trimmed accuracy of ±1%. This frequency enables 1.2 μs A/D conversion and sub-microsecond interrupt response times critical for real-time control loops.
Does the UPD78F0515AGAA2-GAM-G support in-system programming?
Yes, the UPD78F0515AGAA2-GAM-G supports full in-system programming via its on-chip flash memory and integrated self-programming library. The device allows sector-by-sector erase and byte/word programming while running user code, enabling field firmware updates without removing the chip from the PCB. The library is provided by Renesas and validated for 100,000 write/erase cycles.
What are the power supply requirements for analog and digital sections of the UPD78F0515AGAA2-GAM-G?
The UPD78F0515AGAA2-GAM-G requires separate power domains: VDD/EVDD (2.7–5.5 V) for digital logic and EVDD specifically for analog peripherals like the A/D converter and AVREF circuitry. VSS and EVSS must be connected to ground with low-impedance paths. Decoupling capacitors (0.1 μF ceramic near each VDD/EVDD pair) are mandatory to maintain A/D accuracy and prevent digital noise from coupling into analog measurements.
How many serial communication interfaces does the UPD78F0515AGAA2-GAM-G integrate?
The UPD78F0515AGAA2-GAM-G integrates three serial interfaces: one I²C bus interface (supports standard/fast mode), two UART channels (UART0 and UART1, each with independent baud rate generators), and one CSI interface compatible with synchronous serial protocols. These are mapped to dedicated pins on Port 0 and Port 1, allowing concurrent use for multi-protocol bridging applications such as sensor hub or metering gateway designs.
Is the UPD78F0515AGAA2-GAM-G pin-compatible with other 78K0/KC2 devices?
Yes, the UPD78F0515AGAA2-GAM-G shares the same 64-pin LQFP package and pin assignment with other 78K0/KC2 devices including UPD78F0511AGAA2-GAM-G, UPD78F0512AGAA2-GAM-G, and UPD78F0513AGAA2-GAM-G. This allows hardware reuse across variants differing only in flash size (48 KB to 64 KB) and peripheral enablement - simplifying design scalability and inventory management for families of related products.
