Product details
Overview
R5F2136ASDFA#30 from Renesas is a 16-bit R8C CPU core microcontroller with 96 KB flash program ROM, 8 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). It operates at up to 20 MHz (VCC = 2.7–5.5 V), integrates a 28-channel capacitive touch sensor control unit (TSCU), and features UART0 (2 channels), UART2 (1 channel with I²C mode), LIN hardware module, 10-bit × 12-channel ADC, and four independent timers including PWM-capable Timer RC_0. It targets embedded control in consumer appliance HMI subsystems.
For engineers reviewing the R5F2136ASDFA#30 datasheet, R5F2136ASDFA#30 pinout, R5F2136ASDFA#30 application, or R5F2136ASDFA#30 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D version), 64-pin LQFP package (PLQP0064GA-A), integrated TSCU for self-capacitance touch sensing, BGO-enabled data flash for firmware updates without halting execution, and hardware LIN support using UART0_0/UART0_1 or timer RJ_0.
Technical Context
The R5F2136ASDFA#30 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte address space, and a dedicated 16×16→32-bit multiplier with MAC capability. Its clock system includes four independent sources: XIN/XOUT crystal oscillator, XCIN/XCOUT low-power crystal oscillator, high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - all selectable via software-controlled frequency dividers (÷1, ÷2, ÷4, ÷8, ÷16).
Peripheral integration centers on event-driven coordination: the Event Link Controller (ELC) enables 30 sources × 10 event link operations between peripherals without CPU intervention, while the Data Transfer Controller (DTC) provides single-channel DMA with 27 activation sources and repeat/normal transfer modes. The TSCU supports electrostatic capacitive touch detection across 28 channels with system CH × 4 configuration.
