Renesas UPD78F9510GR(R)-JJG-A

Overview

UPD78F9510GR(R)-JJG-A from Renesas Electronics is an 8-bit single-chip microcontroller based on the 78K0S CPU core, featuring 1 KB flash memory, 128 bytes of high-speed RAM, and operation across 2.2–5.5 V supply at –40 to +85°C. It integrates a 16-bit timer/event counter, 8-bit timer H1 with PWM output, watchdog timer, power-on clear, low-voltage detection, and 14 I/O pins (13 CMOS I/O + 1 CMOS input) - used in compact embedded control systems such as appliance motor drivers and sensor interface modules.

For engineers reviewing the UPD78F9510GR(R)-JJG-A datasheet, UPD78F9510GR(R)-JJG-A pinout, UPD78F9510GR(R)-JJG-A application, or UPD78F9510GR(R)-JJG-A equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases, and validated alternative options for industrial and consumer-grade microcontroller selection.

Technical Context

The UPD78F9510GR(R)-JJG-A implements the 78K0S CPU core with 64 KB address space and supports multiple clock sources: 8 MHz internal high-speed oscillator (±5% over –40 to +85°C), external crystal/ceramic (2–10 MHz), or external clock input. Its system clock architecture includes independent low-speed 240 kHz internal oscillator dedicated to watchdog and standby timing.

It provides three integrated timing peripherals: one 16-bit timer/event counter with capture/compare/PWM capabilities, one 8-bit timer H1 supporting PWM output, and one watchdog timer operating independently from the main system clock - enabling robust fault monitoring in safety-critical embedded functions without external supervision.

FAQ

What is the maximum operating frequency supported by UPD78F9510GR(R)-JJG-A?

The UPD78F9510GR(R)-JJG-A supports up to 10 MHz system clock frequency when using external crystal or clock input, delivering a minimum instruction execution time of 0.2 µs. Its internal high-speed oscillator operates at 8 MHz ±5% over the full –40°C to +85°C temperature range, making UPD78F9510GR(R)-JJG-A suitable for stable timing without external components.

Does UPD78F9510GR(R)-JJG-A include an analog-to-digital converter?

No, UPD78F9510GR(R)-JJG-A does not integrate an A/D converter. It is the non-A/D variant in the 78K0S/KY1+ family - distinct from UPD78F9210GR-JJG-A which includes a 10-bit, 4-channel ADC. This omission reduces pin count complexity and cost for purely digital control applications where analog sensing is handled externally.

What package type is used for UPD78F9510GR(R)-JJG-A?

UPD78F9510GR(R)-JJG-A uses the GR-JJG package: a 16-pin plastic SSOP (Shrink Small Outline Package) with 0.65 mm lead pitch and JEDEC MO-153 compliance. This package enables high-density PCB layouts and is compatible with standard reflow soldering processes per J-STD-020.

Can UPD78F9510GR(R)-JJG-A operate from a 3.3 V supply?

Yes, UPD78F9510GR(R)-JJG-A operates across 2.2–5.5 V, fully supporting 3.3 V nominal supply rails. Its internal regulators and I/O buffers are designed for direct interfacing with 3.3 V logic families, and the low-voltage detection (LVI) circuit allows configurable thresholds down to 2.35 V to ensure safe operation during brown-out conditions.

How is the reset function implemented on UPD78F9510GR(R)-JJG-A?

UPD78F9510GR(R)-JJG-A implements reset via the P34/RESET pin - a dedicated active-low input that asserts hardware reset on logic low. During power-on, it functions as RESET regardless of option byte settings; after initialization, P34 may be configured as a general-purpose input port. Internal power-on clear (POC) and low-voltage detection (LVI) also generate reset events autonomously.
