Product details
Overview
UPD78F0545AGCA-GAD-G from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KF2 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 internal high-speed oscillator or external crystal, supports 5V operation, and integrates UART, I²C, and 10-bit ADC for embedded control applications in industrial sensors and motor drives.
For engineers reviewing the UPD78F0545AGCA-GAD-G datasheet, UPD78F0545AGCA-GAD-G pinout, UPD78F0545AGCA-GAD-G application, or UPD78F0545AGCA-GAD-G equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), ADC resolution and conversion time (10-bit, 1.2 μs min), PWM channel count (3-channel), interrupt latency (2–4 cycles), and package compatibility with LQFP-100 footprint.
Technical Context
The UPD78F0545AGCA-GAD-G implements the 78K0 CPU core with 16-bit ALU, 16-level hardware stack, and instruction set optimized for real-time control. It uses a multi-clock domain architecture with separate system, peripheral, and ADC clocks, enabling independent clock gating for power management.
Its on-chip peripherals include three 16-bit timer/counters (one with input capture/compare and PWM output), one 8-bit reload timer, two serial interfaces (UART with LIN support and I²C-compatible interface), and a 10-channel 10-bit successive-approximation ADC with built-in reference voltage and scan mode.

Pinout & Package
This device is housed in a 100-pin LQFP (14 mm × 14 mm, 0.5 mm pitch) package with exposed thermal pad, supporting surface-mount reflow assembly and thermal dissipation up to 1.2 W in typical industrial layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, EVDD | Power supply inputs | Digital and analog core power pins - require separate decoupling (0.1 μF ceramic + 10 μF tantalum) to suppress noise coupling into ADC and timers |
| VSS, EVSS | Ground returns | Digital and analog ground pins - must be connected to low-impedance ground plane with star-point routing near regulator output |
| RESET | Active-low reset input | Asynchronous reset signal - asserted low for ≥100 ns to initialize CPU, registers, and peripherals; internal pull-up enabled by default |
| XTAL1/XTAL2 | Crystal oscillator terminals | Supports fundamental-mode quartz crystals (1–20 MHz); internal load capacitors configurable via SFR for ±10 ppm stability over temperature |
| P00–P07 | Port 0 I/O pins | Bi-directional CMOS I/O with individual direction control; P00–P03 support external interrupt inputs (INT0–INT3) with edge-selectable trigger |
| AD0–AD9 | ADC input channels | Analog input pins mapped to P10–P13, P20–P23, P40–P43 - share physical pins with GPIO; require external RC filter (≤1 kΩ series + 10 nF shunt) for anti-aliasing |
| TXD0/RXD0 | UART0 serial interface | Full-duplex asynchronous communication pins - support LIN bus physical layer (ISO 17987-4) with automatic sync-break detection and wake-up filtering |
| SCL0/SDA0 | I²C interface | Open-drain bidirectional bus pins - support standard (100 kbps) and fast-mode (400 kbps) I²C with slave address auto-acknowledge and arbitration loss detection |
Key Features
| Feature | Design Value |
|---|---|
| On-chip Flash programming | Self-programmable Flash memory enables field firmware updates without external programmer - supports block erase and byte-write with CRC-16 verification |
| Low-power modes | Four operational modes (HALT, STOP, IDLE, and SNOOZE) with wake-up from any interrupt source - STOP mode draws ≤1.2 μA at 5 V |
| ADC scan control | Hardware-triggered sequential conversion across up to 10 channels with automatic result storage in RAM - eliminates CPU polling overhead |
| PWM dead-time insertion | Programmable dead-time (62.5 ns to 1000 ns steps) between complementary PWM outputs - prevents shoot-through in half-bridge motor drivers |
| Watchdog timer | Dedicated 14-bit free-running watchdog with windowed enable and independent clock source - resets CPU if software fails to refresh within defined window |
| On-chip voltage regulator | Integrated 3.3 V LDO for internal analog circuitry - eliminates need for external regulator when using internal ADC and reference |

FAQ
What is the maximum operating frequency of the UPD78F0545AGCA-GAD-G?
The UPD78F0545AGCA-GAD-G supports a maximum system clock frequency of 20 MHz. This can be achieved using either the internal high-speed oscillator (HOC) or an external crystal/resonator connected to XTAL1/XTAL2 pins. At 20 MHz, the instruction cycle time is 200 ns, enabling deterministic real-time response for time-critical control loops in motor and sensor applications. The UPD78F0545AGCA-GAD-G maintains full peripheral functionality-including ADC, UART, and PWM-at this maximum frequency.
Does the UPD78F0545AGCA-GAD-G include an on-chip voltage regulator?
Yes, the UPD78F0545AGCA-GAD-G integrates an on-chip 3.3 V LDO regulator dedicated to powering internal analog circuits, including the ADC reference and oscillator circuitry. This eliminates the need for an external low-noise regulator when using the internal ADC and improves system-level noise immunity. The UPD78F0545AGCA-GAD-G still requires external 5 V supply on VDD/EVDD pins, and the LDO output is not accessible externally.
How many ADC input channels does the UPD78F0545AGCA-GAD-G support?
The UPD78F0545AGCA-GAD-G features a 10-bit successive-approximation ADC with 10 selectable input channels (AD0–AD9), mapped across multiple port pins (P10–P13, P20–P23, P40–P43). These channels support hardware-triggered scan mode, allowing sequential conversion without CPU intervention. The UPD78F0545AGCA-GAD-G achieves a minimum conversion time of 1.2 μs per channel under optimal clock configuration.
Is the UPD78F0545AGCA-GAD-G pin-compatible with other 78K0/KF2 devices?
Yes, the UPD78F0545AGCA-GAD-G is pin-compatible with all members of the 78K0/KF2 family in the 100-pin LQFP package, including UPD78F0544AGCA-GAD-G, UPD78F0546AGCA-GAD-G, and UPD78F0547AGCA-GAD-G. Pin functions, power domains, and peripheral mappings are consistent across these variants, enabling hardware reuse when scaling Flash size (64 KB → 128 KB) or adjusting peripheral mix (e.g., adding CAN).
What development tools are supported for the UPD78F0545AGCA-GAD-G?
The UPD78F0545AGCA-GAD-G is supported by Renesas' legacy 78K0 toolchain, including the RA78K0 assembler (v4.01), CC78K0 C compiler (v4.00), QB-MINI2 on-chip debugger, and PG-FP5 Flash programmer. Application notes U17516E (Self Programming) and U17739E (Flash Programming) provide validated procedures for firmware update and production programming. The UPD78F0545AGCA-GAD-G does not support modern e2 studio or CS+ IDE natively.
