Renesas UPD78F0536AFC-AA1-A

Overview

UPD78F0536AFC-AA1-A from Renesas Electronics is an 8-bit single-chip microcontroller in the 78K0/KE2 family, featuring 64 KB on-chip flash memory, 4 KB RAM, and a 16-bit timer with PWM output capability. It operates at up to 20 MHz CPU clock frequency using an internal high-speed oscillator or external crystal, supports 10-bit ADC with 16 channels, and targets embedded control applications in industrial equipment and consumer appliances.

For engineers reviewing the UPD78F0536AFC-AA1-A datasheet, UPD78F0536AFC-AA1-A pinout, UPD78F0536AFC-AA1-A application, or UPD78F0536AFC-AA1-A equivalent, key selection criteria include flash endurance (100,000 write/erase cycles), operating voltage range (2.7–5.5 V), and support for on-chip debug via single-wire interface - all confirmed for this exact variant.

Technical Context

The UPD78F0536AFC-AA1-A implements the 78K0 CPU core with 16-bit address space and supports both conventional- and expanded-specification features. Its expanded-specification status confirms faster A/D conversion time (≤1.6 μs per channel), tighter X1 oscillator stability (±0.5% over temperature), and improved flash self-programming interrupt response (≤3.2 μs).

It integrates dedicated hardware peripherals including a serial array unit (SAU) supporting UART, CSI, and I²C modes; a watchdog timer with independent clock source; and power-on reset with built-in voltage detector (VDD = 2.7 V threshold). All are active within the specified 2.7–5.5 V supply range and −40°C to +85°C ambient temperature.

FAQ

What is the maximum operating frequency of the UPD78F0536AFC-AA1-A?

The UPD78F0536AFC-AA1-A supports a maximum CPU clock frequency of 20 MHz. This can be achieved using either the internal high-speed oscillator (with optional trimming) or an external crystal/resonator up to 20 MHz. The instruction cycle time is 0.05 μs at 20 MHz, enabling deterministic real-time response for time-critical control loops. All timing specifications in the hardware manual are validated for this exact part number under standard industrial conditions.

Does the UPD78F0536AFC-AA1-A support in-system programming (ISP)?

Yes, the UPD78F0536AFC-AA1-A supports in-system programming via its on-chip debug interface using single-wire mode. Firmware updates can be performed without removing the device from the target board, leveraging the built-in flash self-programming library. This capability is confirmed for the UPD78F0536AFC-AA1-A variant in Renesas Application Note U17516E and requires no external programming hardware beyond a standard SWD debugger.

What is the flash memory endurance rating for the UPD78F0536AFC-AA1-A?

The UPD78F0536AFC-AA1-A guarantees 100,000 write/erase cycles for its 64 KB on-chip flash memory, with data retention of 20 years at 85°C ambient temperature. This endurance rating is explicitly stated for expanded-specification 78K0/KE2 devices including UPD78F0536AFC-AA1-A in the Flash Memory Programming User's Manual (U17739E) and applies across the full industrial temperature range.

Is the UPD78F0536AFC-AA1-A pin-compatible with other 78K0/KE2 microcontrollers?

The UPD78F0536AFC-AA1-A shares the same 100-pin LQFP package and pin assignment with other 78K0/KE2 devices in the same package variant, including UPD78F0537AFC-AA1-A and UPD78F0535AFC-AA1-A. However, functional differences exist in flash size, RAM allocation, and peripheral enablement - so while physical layout is identical, firmware and configuration must match the specific part's resource map.

What development tools are officially supported for the UPD78F0536AFC-AA1-A?

Renesas officially supports the QB-MINI2 on-chip debug emulator and the RA78K0 assembler toolchain (Ver. 4.01) for the UPD78F0536AFC-AA1-A. The CC78K0 C compiler (Ver. 4.00) and ID78K0-QB integrated debugger are also validated. All tools are documented in the 78K0/Kx2 User's Manual (R01UH0008EJ0401) and require no hardware modification to work with UPD78F0536AFC-AA1-A in standard configuration.
