It operates at up to 20 MHz (2.7–5.5 V) or 8 MHz (1.8–5.5 V), supports real-time clock (Timer RH), three 16-bit Timer RJ units, 12-channel 10-bit A/D converter, and UART0/UART2 with I²C mode - deployed in appliance control panels requiring low-power, integrated display driving and sensor interfacing.
For engineers reviewing the R5F2LA8AANFA#V0 datasheet, R5F2LA8AANFA#V0 pinout, R5F2LA8AANFA#V0 application, or R5F2LA8AANFA#V0 equivalent, key selection criteria include its 80-pin LQFP (0.65 mm pitch) package, −20 to +85°C N-version temperature rating, on-chip debug capability, data flash endurance (10,000 write/erase cycles), and support for wait/stop/power-off low-power modes down to 0.01 µA.
Technical Context
The R5F2LA8AANFA#V0 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability. Its memory architecture includes 96 KB program ROM, dual 2 KB data flash banks, and 5.5 KB RAM - enabling robust firmware updates and parameter storage without external EEPROM.
