Product details
Overview
R5F2L36ACNFA#31 from Renesas is a 16-bit R8C/L36C Group microcontroller featuring an R8C CPU core, 96 KB flash program memory, 1 KB × 4 data flash with background operation (BGO), 10-bit × 10-channel ADC, and integrated LCD drive supporting up to 8 common and 32 segment outputs. It operates at up to 20 MHz (50 ns min instruction time) with 52 programmable I/O pins and targets embedded control in cost-sensitive consumer appliances.
For engineers reviewing the R5F2L36ACNFA#31 datasheet, R5F2L36ACNFA#31 pinout, R5F2L36ACNFA#31 application, or R5F2L36ACNFA#31 equivalent, key selection criteria include its 64-pin LQFP package (0.80 mm pitch), -20°C to +85°C temperature grade (N version), integrated LIN module using Timer RA and UART0, and support for low-power wait/stop modes down to 3.5 µA and 2 µA respectively.
Technical Context
The R5F2L36ACNFA#31 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit hardware multiplier enabling efficient signal processing and control loop execution. Its system clock generation includes four independent circuits: XIN oscillator (up to 20 MHz), XCIN 32 kHz crystal input, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software.
Peripheral integration centers on mixed-signal timing and interface functions: Timer RD provides three-phase PWM with complementary output (6 pins), Timer RC supports 3-pin PWM, UART0/1/2 offer serial communication with I²C-bus mode on UART2, and the DTC enables autonomous data transfers triggered by 38 sources including ADC completion and timer overflows.
