160 MHz RXv3 core with balanced on-chip memory
The Renesas R5F566TEFDFL#30 is a 32-bit microcontroller built around the RXv3 CPU core, clocked at 160 MHz. It carries 512 KB of program Flash, 64 KB of SRAM, and 32 KB of data EEPROM on a single die, which keeps the BOM lean for applications that need moderate code space and nonvolatile parameter storage without an external serial EEPROM.
Connectivity and analog I/O for mixed-signal control
The 33 general-purpose I/O lines are enough to handle a keypad, a small TFT display, and a few sensor inputs. For analog front-end tasks, there are eight 12-bit ADC channels and two 12-bit DAC outputs, which cover current sensing, temperature monitoring, and analog set-point generation without an external converter.
Package and rework considerations
The part comes in a 48-LQFP (7x7 mm body) with a 0.5 mm pitch. That pitch is fine for a standard reflow profile, and the exposed pad on the LFQFP variant helps thermal dissipation if the MCU drives a lot of I/O simultaneously.
