Product details
Overview
UPD78F0078GC-8BS-A from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K/0 Series, featuring 64 KB on-chip flash memory, 3.5 KB RAM, and integrated peripherals including UART0, UART2, SIO3, CSI1, 16-bit timers, 8-bit timers, A/D converter (8-channel, 10-bit), and watchdog timer. It operates at up to 20 MHz with supply voltage range 2.7–5.5 V and targets embedded control in industrial appliances and office equipment.
For engineers reviewing the UPD78F0078GC-8BS-A datasheet, UPD78F0078GC-8BS-A pinout, UPD78F0078GC-8BS-A application, or UPD78F0078GC-8BS-A equivalent, key selection considerations include its 80-pin LQFP package, flash-based programmability, I/O count (64 pins), 10-bit ADC resolution, and support for IEBus-compatible serial communication via CSI1.
Technical Context
The UPD78F0078GC-8BS-A implements the 78K/0 CPU core with Harvard architecture, supporting 16-bit address space and 8-bit data path. It integrates a clock generator with internal oscillator (1 MHz) and external crystal support (1–20 MHz via X1/X2), plus standby and reset functions compliant with JEDEC JESD78 Class II.
Peripheral integration includes three independent serial interfaces: UART0 (full-duplex asynchronous), UART2 (full-duplex asynchronous with automatic baud rate detection), and CSI1 (synchronous serial interface compatible with IEBus physical layer). The A/D converter supports single- and continuous-conversion modes with software/start-triggered sampling.

FAQ
What is the maximum operating frequency of the UPD78F0078GC-8BS-A?
The UPD78F0078GC-8BS-A operates at a maximum frequency of 20 MHz when powered at 4.5–5.5 V. At lower supply voltages (2.7–4.4 V), the maximum frequency is reduced to 10 MHz per the electrical specifications in Chapter 25 of the U14260EJ4V0UD User's Manual. This scaling ensures stable timing margin across the full voltage range.
Does the UPD78F0078GC-8BS-A support in-system programming (ISP)?
Yes, the UPD78F0078GC-8BS-A supports in-system programming via its on-chip flash memory. Programming is performed through the dedicated VPP pin (pin 79) using a standard Renesas PG-FP4 programmer or compatible tool. The device requires no external ROM socket, enabling firmware updates directly on the target board without removal.
Which serial interfaces are available on the UPD78F0078GC-8BS-A?
The UPD78F0078GC-8BS-A integrates three serial interfaces: UART0 (asynchronous, full-duplex), UART2 (asynchronous with auto-baud detection), and CSI1 (synchronous, IEBus-physical-layer compatible). UART0 and UART2 share P00/P01 and P20/P21 respectively; CSI1 uses P02/P03. No I²C or SPI hardware blocks are present.
What is the ADC resolution and channel count of the UPD78F0078GC-8BS-A?
The UPD78F0078GC-8BS-A features an 8-channel, 10-bit successive-approximation A/D converter. It achieves ±1 LSB integral nonlinearity (INL) and supports both single-shot and continuous conversion modes. Input channels map to P30–P36 and P40, with separate analog reference pins (AVREF, AVSS) for precision measurement.
Is the UPD78F0078GC-8BS-A pin-compatible with other devices in the 78K/0 Series?
The UPD78F0078GC-8BS-A shares the same 80-pin LQFP package and core pinout with other members of the µPD78F0078 subseries (e.g., UPD78F0076GC-8BS-A), but is not pin-compatible with Y-subseries variants (e.g., UPD78F0078YGC-8BS-A) due to differences in I²C0 pin allocation. Always verify pin function mapping against Chapter 3 of U14260EJ4V0UD before substitution.
