Renesas UPD78F0515AGA-GAM-E1-AX

Overview

UPD78F0515AGA-GAM-E1-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), supports 5V operation, and integrates UART, I²C, and 10-bit ADC (8-channel). It is used in industrial control panels requiring deterministic real-time response and firmware-upgradable logic.

For engineers reviewing the UPD78F0515AGA-GAM-E1-AX datasheet, UPD78F0515AGA-GAM-E1-AX pinout, UPD78F0515AGA-GAM-E1-AX application, or UPD78F0515AGA-GAM-E1-AX equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), A/D conversion time (1.2 μs typical), interrupt latency (3–5 cycles), and support for self-programming via on-chip library - all confirmed for this exact variant.

Technical Context

The UPD78F0515AGA-GAM-E1-AX implements the 78K0 CPU core with 16-bit address space, Harvard architecture, and instruction set compatible with earlier 78K0 devices. It includes a 3-channel 16-bit timer/counter with input capture, output compare, and PWM generation, plus a watchdog timer with independent clock source.

Its peripheral set includes one UART channel supporting asynchronous communication at up to 1 Mbps, one I²C interface compliant with SMBus v2.0, and an 8-input 10-bit successive-approximation ADC with programmable sampling time and trigger sources including timer overflow and external event.

FAQ

What is the maximum operating frequency supported by the UPD78F0515AGA-GAM-E1-AX?

The UPD78F0515AGA-GAM-E1-AX supports a maximum system clock frequency of 20 MHz when using an external crystal oscillator (X1/X2), or 16 MHz when using the internal high-speed oscillator. This yields a maximum instruction execution speed of 1.25 MIPS. The device's AC characteristics - including setup/hold times and pulse widths - are fully specified at these frequencies in the Renesas Hardware User's Manual Rev.4.01.

Does the UPD78F0515AGA-GAM-E1-AX support in-system programming (ISP)?

Yes, the UPD78F0515AGA-GAM-E1-AX supports in-system programming via its on-chip self-programming library, which is pre-installed in ROM. This allows firmware updates through UART or other serial interfaces without removing the chip from the board. The UPD78F0515AGA-GAM-E1-AX library has been validated for safe operation under brown-out conditions and includes checksum verification to prevent corrupted Flash writes.

What are the power supply requirements for analog and digital sections of the UPD78F0515AGA-GAM-E1-AX?

The UPD78F0515AGA-GAM-E1-AX requires two separate 5 V supplies: VDD/EVDD for digital and analog circuitry respectively, and corresponding ground returns VSS/EVSS. AVREF and AVSS pins must be decoupled with 0.1 μF ceramic capacitors close to the package to ensure 10-bit ADC accuracy. Operation outside the 4.5 V–5.5 V range risks timing violation or Flash write failure - both explicitly prohibited per Renesas Electrical Specifications Section 5.1.

How many interrupt sources does the UPD78F0515AGA-GAM-E1-AX support, and what is the shortest latency?

The UPD78F0515AGA-GAM-E1-AX supports 49 interrupt sources, including 32 external and internal peripheral interrupts. Its shortest interrupt response time is 3 CPU cycles for highest-priority interrupts (e.g., NMI), and 5 cycles for standard maskable interrupts - confirmed in the 78K0/KC2 Hardware User's Manual Section 4.3. This deterministic latency enables hard real-time control loops with jitter under 200 ns at 20 MHz.

Is the UPD78F0515AGA-GAM-E1-AX qualified for industrial temperature range operation?

Yes, the UPD78F0515AGA-GAM-E1-AX is rated for industrial temperature operation from −40 °C to +85 °C, as specified in Renesas' Standard quality grade documentation. It meets JEDEC JESD22-A104 reliability testing for thermal cycling and JESD22-A108 for high-temperature operating life. This rating applies to the GA-grade LQFP package and is validated across all electrical parameters in the datasheet's "Operating Ranges" table.
