Overview

UPD78F0058YGC-8BT-A from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K/0 Series, featuring 64 KB flash memory, 2 KB RAM, and integrated peripherals including 10-bit A/D converter (8 channels), D/A converter (2 channels), three serial interfaces (UART, CSI, I²C), and multiple timers. It operates at up to 20 MHz with supply voltage range of 2.2 V to 5.5 V and targets embedded control in industrial sensors and appliance motor control.

For engineers reviewing the UPD78F0058YGC-8BT-A datasheet, UPD78F0058YGC-8BT-A pinout, UPD78F0058YGC-8BT-A application, or UPD78F0058YGC-8BT-A equivalent, key selection criteria include flash endurance (10,000 write/erase cycles), I²C bus support (standard-mode only), 80-pin TQFP package compatibility, and compliance with Standard quality grade for non-safety-critical industrial use.

Technical Context

This microcontroller implements the 78K0 CPU core with Harvard architecture, supporting 16-bit addressing and 128 KB address space. It integrates a programmable clock generator with on-chip oscillator (1 to 20 MHz), PLL circuit for frequency multiplication, and multiple clock sources including external crystal, ceramic resonator, or RC oscillator.

The peripheral set includes two 16-bit timer/event counters (TI00/TI01) with PPG output capability, one 8-bit timer/event counter, watchdog timer, real-time output port, and three independent serial interface channels - UART (SCI), 3-wire/2-wire CSI, and I²C bus mode - all configurable via dedicated control registers.

FAQ

What is the maximum operating frequency of the UPD78F0058YGC-8BT-A?

The UPD78F0058YGC-8BT-A supports a maximum CPU clock frequency of 20 MHz when powered within its specified supply voltage range of 2.2 V to 5.5 V. This frequency is achieved using the on-chip PLL with external crystal or resonator input on X1/X2 pins. At 20 MHz, the instruction execution time is 200 ns per basic instruction cycle, enabling deterministic real-time response in motor control and sensor acquisition loops. The UPD78F0058YGC-8BT-A maintains full peripheral functionality-including A/D conversion, UART, and I²C-at this maximum clock rate.

Does the UPD78F0058YGC-8BT-A support I²C bus communication?

Yes, the UPD78F0058YGC-8BT-A includes dedicated hardware support for I²C bus communication via SCL and SDA pins. It operates in standard-mode only (up to 100 kbps) and supports both master and slave roles. The I²C module features automatic start/stop condition generation, ACK/NACK handling, and arbitration loss detection-eliminating software bit-banging overhead. Pull-up resistors must be externally connected to SCL and SDA, as internal pull-ups are disabled by default. This I²C capability is confirmed in Chapter 17 of the UPD78F0058YGC-8BT-A User's Manual (U12013EJ3V2UD).

What are the analog capabilities of the UPD78F0058YGC-8BT-A?

The UPD78F0058YGC-8BT-A integrates an 8-channel, 10-bit successive-approximation A/D converter with 10 µs typical conversion time at 20 MHz operation, and two independent 8-bit voltage-output D/A converters. The A/D converter accepts inputs referenced to AVREF0 (1.5–5.5 V), while the D/A outputs are scaled relative to AVREF1. Both analog blocks share common design constraints: ANI0–ANI7 pins have ≤10 kΩ recommended source impedance, and DA0/DA1 outputs drive loads ≥10 kΩ. These specifications are documented in Chapters 14 and 15 of the UPD78F0058YGC-8BT-A User's Manual.

What package type and pin count does the UPD78F0058YGC-8BT-A use?

The UPD78F0058YGC-8BT-A uses an 80-pin plastic TQFP package (GK-9EU type) with 0.5 mm lead pitch, conforming to JEDEC MO-140. This package replaces earlier GC-3B9 and GK-BE9 variants and is explicitly listed in the "Major Revisions" section of the UPD78F0058YGC-8BT-A User's Manual (U12013EJ3V2UD, p.6). The pinout is fully defined in Chapter 4 ("Pin Functions") of that manual, including dedicated functions for A/D inputs (ANI0–ANI7), D/A outputs (DA0, DA1), and I²C interface (SCL, SDA). Thermal and mechanical dimensions are provided in Chapter 32.

Is the UPD78F0058YGC-8BT-A qualified for automotive applications?

No, the UPD78F0058YGC-8BT-A is classified under the "Standard" quality grade per Renesas documentation, intended for computers, office equipment, communications gear, audio/video devices, home appliances, and industrial robots. It is not qualified for automotive use, which requires "High Quality" grade parts meeting AEC-Q100 stress testing and extended temperature ranges (−40°C to +125°C). The UPD78F0058YGC-8BT-A is rated for −20°C to +75°C ambient operation and lacks automotive-specific qualification evidence in its datasheet or user manual. For automotive applications, Renesas recommends RL78/F1x or RH850 families instead.
