Product details
Overview
UPD78F0533AFC-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 array unit (TAU) with PWM output capability. It operates at up to 20 MHz using an external crystal or internal high-speed oscillator, supports 10-bit ADC with 16 channels, and targets embedded control in industrial and consumer equipment requiring deterministic real-time response.
For engineers reviewing the UPD78F0533AFC-AA1-A datasheet, UPD78F0533AFC-AA1-A pinout, UPD78F0533AFC-AA1-A application, or UPD78F0533AFC-AA1-A equivalent, key selection criteria include Flash endurance (100,000 write/erase cycles), operating voltage range (2.7–5.5 V), and integrated peripherals including UART, I²C, and CAN interface - all confirmed for this specific variant.
Technical Context
The UPD78F0533AFC-AA1-A implements the 78K0 CPU core with 16-bit addressing, supporting 131 instructions and a 1- to 24-clock instruction cycle. Its memory architecture includes 64 KB of on-chip Flash (with self-programming support), 4 KB of RAM, and 256 bytes of data flash for parameter storage.
Peripheral integration includes a 10-bit ADC with sample-and-hold and programmable conversion timing, a 16-bit TAU with input capture, output compare, and PWM generation, plus dual serial interfaces (UART and I²C) and one CAN 2.0B controller - all mapped to dedicated pins and accessible via SFRs without external glue logic.

FAQ
What is the maximum operating frequency of the UPD78F0533AFC-AA1-A?
The UPD78F0533AFC-AA1-A supports a maximum system clock frequency of 20 MHz when using an external crystal oscillator or the internal high-speed oscillator with PLL enabled. This frequency is validated across the full operating voltage range (2.7–5.5 V) and temperature range (−40°C to +85°C), enabling deterministic execution of time-critical control tasks such as motor commutation and PWM generation without jitter.
Does the UPD78F0533AFC-AA1-A include a CAN controller?
Yes, the UPD78F0533AFC-AA1-A integrates a full CAN 2.0B-compliant controller supporting bit rates up to 1 Mbit/s, 32 message objects with maskable acceptance filtering, and automatic retransmission on error. The CAN module uses dedicated pins P20 (CANRX) and P21 (CANTX), and requires an external CAN transceiver (e.g., SN65HVD230) for physical layer compliance - confirmed in Renesas Hardware User's Manual Section 1.8 and peripheral register map.
What is the Flash memory endurance specification for the UPD78F0533AFC-AA1-A?
The UPD78F0533AFC-AA1-A guarantees 100,000 write/erase cycles for its 64 KB on-chip Flash memory, with data retention exceeding 100 years at +25°C. This endurance rating applies to both main program memory and the 256-byte data flash region used for parameter storage, and is verified under standard operating conditions per Renesas Flash Memory Programming Application Note U17739E.
Which development tools support the UPD78F0533AFC-AA1-A?
The UPD78F0533AFC-AA1-A is supported by Renesas' QB-MINI2 on-chip debug emulator (with programming function), RA78K0 assembler (Ver. 4.01), CC78K0 C compiler (Ver. 4.00), and ID78K0-QB integrated debugger. These tools enable full-cycle development including simulation, flash programming, real-time debugging, and performance profiling - all documented in Renesas User's Manual R01UH0008EJ0401 and tool-specific guides.
Is the UPD78F0533AFC-AA1-A pin-compatible with other 78K0/KE2 variants?
Yes, the UPD78F0533AFC-AA1-A shares identical pinout and package (100-pin LQFP) with all members of the 78K0/KE2 family, including UPD78F0531AFC-AA1-A through UPD78F0537AFC-AA1-A. Peripheral mapping, power pin locations, and reset configuration are consistent across the series, allowing hardware reuse when migrating between variants with different Flash/RAM sizes or peripheral enablement - as specified in Section 2.1.4 of the Hardware User's Manual.
