Renesas UPD78F0560MC-CAA-AX

Overview

UPD78F0560MC-CAA-AX from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KA2-L family, featuring 64 KB on-chip Flash memory, 4 KB RAM, and a 20 MHz max CPU clock. It integrates UART, I²C, 16-bit timer/counters, ADC (8-channel, 10-bit), and operates from 2.7–5.5 V supply. Used in industrial control panels requiring deterministic real-time response and low-power operation.

For engineers reviewing the UPD78F0560MC-CAA-AX datasheet, UPD78F0560MC-CAA-AX pinout, UPD78F0560MC-CAA-AX application, or UPD78F0560MC-CAA-AX equivalent, key selection criteria include Flash endurance (100k write/erase cycles), built-in voltage regulator (V_REG output), and support for low-power stop modes with wake-up via external interrupt or RTC alarm - critical for battery-backed sensor nodes and programmable logic controllers.

Technical Context

The UPD78F0560MC-CAA-AX implements the 78K0S CPU core with 16-bit address space, supporting 131 instructions including bit manipulation and conditional skip. Its clock system includes internal high-speed oscillator (HSO) and external crystal options (X1: 1–20 MHz), with programmable PLL for precise frequency synthesis.

Peripheral integration follows a tightly coupled architecture: ADC conversion triggers DMA transfers without CPU intervention; UART supports asynchronous mode with framing error detection; and port P12 functions as dedicated I²C interface with open-drain control and slew-rate limiting - all configurable via SFRs mapped to fixed memory addresses (e.g., ADM0 at 00F0H).

Key Specifications

Pinout & Package

UPD78F0560MC-CAA-AX is housed in a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments follow Renesas' standard 78K0/KA2-L layout, supporting dual-voltage I/O (5 V tolerant on selected ports) and dedicated reset/wake-up inputs.

FAQ

What is the maximum operating frequency of the UPD78F0560MC-CAA-AX?

The UPD78F0560MC-CAA-AX supports a maximum CPU clock frequency of 20 MHz when using the on-chip PLL with an external crystal or internal high-speed oscillator. This yields up to 20 MIPS performance for time-critical control loops, verified under 2.7–5.5 V supply and −40 °C to +85 °C operating conditions per Renesas Hardware User's Manual Rev.4.00.

Does the UPD78F0560MC-CAA-AX include an integrated voltage regulator?

Yes, the UPD78F0560MC-CAA-AX features an on-chip voltage regulator that generates a stable 3.3 V supply (V_REG) from the main VDD input. It requires an external 1 µF ceramic capacitor connected to the REGC pin, enabling simplified power architecture for mixed-signal applications without needing an external LDO.

How many ADC channels does the UPD78F0560MC-CAA-AX support, and what is their resolution?

The UPD78F0560MC-CAA-AX integrates an 8-channel, 10-bit successive approximation ADC. All eight channels (AN0–AN7) are accessible via Port 2 pins and support programmable sampling time, trigger sources (software/timer/external), and result alignment - delivering ±1 LSB integral nonlinearity for precision analog measurement in UPD78F0560MC-CAA-AX-based systems.

Is the UPD78F0560MC-CAA-AX pin-compatible with other 78K0/KA2-L family members?

The UPD78F0560MC-CAA-AX uses the standard 64-pin LQFP package shared across the 78K0/KA2-L family, including UPD78F0561 and UPD78F0562. Pin functions are consistent per port group (e.g., P0–P4, P6–P7, P12), though Flash size and peripheral enablement differ - allowing PCB reuse when migrating within the same package variant.

What low-power modes are supported by the UPD78F0560MC-CAA-AX?

The UPD78F0560MC-CAA-AX supports three hardware-controlled low-power modes: HALT (CPU stopped, peripherals active), STOP (CPU and most peripherals halted, RAM retained), and SNOOZE (selected peripherals like RTC and UART remain active). Wake-up is possible via external interrupt, RTC alarm, or key return - achieving sub-µA current in SNOOZE mode for UPD78F0560MC-CAA-AX battery applications.
