Product details
Overview
UPD78F0058GK-9EU-A from Renesas Electronics is an 8-bit Flash-based microcontroller in the 78K/0 Series, featuring 64 KB on-chip Flash memory, 4 KB RAM, and integrated peripherals including 16-bit timer/event counter, 8-bit timer, A/D converter (8-channel, 10-bit), D/A converter (2-channel, 8-bit), and three serial interface channels (UART, CSI, I²C). 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 drivers.
For engineers reviewing the UPD78F0058GK-9EU-A datasheet, UPD78F0058GK-9EU-A pinout, UPD78F0058GK-9EU-A application, or UPD78F0058GK-9EU-A equivalent, key selection criteria include Flash memory size, A/D resolution and channel count, I²C bus support, operating voltage margin down to 2.2 V, and TQFP-80 package compatibility for space-constrained PCB layouts.
Technical Context
This MCU implements the 78K/0 CPU core with 16-bit address space and supports both mask ROM and Flash variants. Its peripheral set includes dual serial interface channels (SCI0 and SCI1) with UART/CSI modes, plus SCI2 supporting I²C bus mode - a distinguishing feature versus the non-Y subseries.
The device integrates analog functions: an 8-input, 10-bit successive-approximation A/D converter with sampling time ≤1.5 µs, and two independent 8-bit D/A converters with built-in reference buffers. Clock generation supports internal high-speed oscillator (up to 20 MHz), sub-clock (32.768 kHz), and external crystal options.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 78K/0 8-bit CPU with 16-bit addressing; enables compact code footprint and deterministic real-time interrupt latency. |
| Flash Memory | 64 KB on-chip Flash; supports in-system programming and field firmware updates without external programmer. |
| RAM Size | 4 KB on-chip RAM; sufficient for stack, variables, and small buffer handling in sensor or motor control tasks. |
| A/D Converter | 8-channel, 10-bit SAR ADC; provides ≥1 LSB integral nonlinearity and supports simultaneous sampling across multiple inputs. |
| D/A Converter | 2-channel, 8-bit voltage-output DAC; each channel drives resistive loads up to 1 mA with ±1 LSB accuracy. |
| Serial Interfaces | SCI0 (UART/CSI), SCI1 (UART/CSI), SCI2 (I²C); enables multi-protocol communication with sensors, displays, and host controllers. |
| Supply Voltage | 2.2 V to 5.5 V operation; ensures reliable function across battery-powered (e.g., 2×AA) and regulated 3.3 V/5 V systems. |
| Package | 80-pin plastic TQFP (GK-9EU type); 12 mm × 12 mm body, 0.5 mm pitch - compatible with standard SMT reflow profiles. |
Pinout & Package
The UPD78F0058GK-9EU-A is housed in an 80-pin plastic TQFP (GK-9EU type) package with 0.5 mm lead pitch and exposed thermal pad. Pin functions are defined per Chapter 4 of the User's Manual U12013EJ3V2UD for the µPD780058Y Subseries.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual VDD/VSS pairs ensure stable core and I/O domain operation; decoupling required per pin group. |
| P00–P07 | Port 0 bidirectional I/O | Configurable as general-purpose I/O or alternate functions including INTP0/TI00, enabling external interrupt or timer input capture. |
| P10–P17 | Port 1 bidirectional I/O | Supports UART TXD0/RXD0, CSI0SCK/CSI0SO, and I²C SCL0/SDA0 - critical for serial peripheral interfacing. |
| P20–P27 | Port 2 bidirectional I/O | Includes A/D input ANI0–ANI7 and D/A output DAO0/DAO1; direct analog signal acquisition and control without external DAC. |
| XT1, XT2 | Crystal oscillator terminals | Supports 1–20 MHz external crystal; internal oscillator can be selected for cost-sensitive applications without crystal. |
| AVREF0, AVREF1 | Analog reference inputs | AVREF0 sets A/D reference (2.2–5.5 V); AVREF1 sets D/A reference (2.2–5.5 V); allows independent scaling of analog domains. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100PLAFB#30 | RL78/G13 core, 64 KB Flash, 4 KB RAM, but only 8-bit A/D (8 ch), no on-chip D/A; operates down to 1.6 V. | Lacks dual D/A outputs and I²C hardware; requires external DAC for analog setpoint generation. | Select when ultra-low-voltage operation (<2.2 V) or lower active power is prioritized over analog integration. |
| UPD78F0532GA-UEU-AX | Same 78K/0 core, 128 KB Flash, 8 KB RAM, adds CAN interface and enhanced PWM; same 2.2–5.5 V range and TQFP-80 package. | Includes CAN physical layer support and higher-resolution PWM - suited for automotive body electronics. | Select when CAN bus connectivity or expanded memory is required; pin-compatible but not drop-in due to different peripheral register mapping. |
Compared with UPD78F0058GK-9EU-A, R5F100PLAFB#30 trades analog integration for lower voltage operation, while UPD78F0532GA-UEU-AX extends functionality with CAN and larger memory - neither offers identical analog peripheral complement in the same package footprint.

FAQ
What is the maximum operating frequency of the UPD78F0058GK-9EU-A?
The UPD78F0058GK-9EU-A operates at a maximum CPU clock frequency of 20 MHz. This is achievable using the internal high-speed oscillator or an external crystal up to 20 MHz. The device maintains full functionality-including A/D conversion, serial communication, and timer operations-at this speed across its specified supply voltage range of 2.2 V to 5.5 V, as confirmed in Chapter 29 of the electrical specifications.
Does the UPD78F0058GK-9EU-A support I²C communication?
Yes, the UPD78F0058GK-9EU-A supports hardware I²C communication via Serial Interface Channel 2 (SCI2), as documented in Chapter 17 of the User's Manual U12013EJ3V2UD. It implements full I²C master and slave modes with clock stretching, 7-bit and 10-bit addressing, and arbitration-enabling direct connection to I²C sensors, EEPROMs, and displays without software bit-banging.
What are the analog input and output capabilities of the UPD78F0058GK-9EU-A?
The UPD78F0058GK-9EU-A integrates an 8-channel, 10-bit successive-approximation A/D converter (ANI0–ANI7) and two independent 8-bit voltage-output D/A converters (DAO0, DAO1). A/D conversion time is ≤1.5 µs; D/A output accuracy is ±1 LSB. Both analog sections use separate reference inputs (AVREF0 and AVREF1), allowing independent scaling for acquisition and control loops.
Is the UPD78F0058GK-9EU-A pin-compatible with other devices in the 78K/0 family?
The UPD78F0058GK-9EU-A uses the GK-9EU 80-pin TQFP package, which is shared with other members of the µPD780058Y Subseries (e.g., UPD78F0058Y). However, it is not pin-compatible with non-Y subseries parts like UPD780058, which lack I²C support on SCI2 and have different serial mode allocations. Pin mapping must be verified against Chapter 4 of the U12013EJ3V2UD manual.
What development tools are supported for the UPD78F0058GK-9EU-A?
Renesas provides full toolchain support for the UPD78F0058GK-9EU-A, including the CC78K0 C compiler (U14297E/U14298E), RA78K0 assembler (U14445E), ID78K Series integrated debugger (U15185E), and PG-FP4 Flash memory programmer (U15260E). These tools are validated for Flash programming, real-time debugging, and peripheral configuration - all referenced in Appendix B of the User's Manual.
