Product details
Overview
R5F2136CSNFP#30 from Renesas Electronics is a 16-bit R8C CPU core-based microcontroller with 128 KB flash program ROM, 10 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 10-bit × 12-channel A/D converter, electrostatic capacitive touch sensor control unit (28 channels), and hardware LIN module. It targets embedded control in consumer audio equipment and household appliances requiring low EMI/EMS and integrated analog sensing.
For engineers reviewing the R5F2136CSNFP#30 datasheet, R5F2136CSNFP#30 pinout, R5F2136CSNFP#30 application, or R5F2136CSNFP#30 equivalent, this MCU offers confirmed support for UART0 (2 channels), UART2 (I²C/LIN-capable), SSU/I²C, 4 timer units (RJ/RB2/RC/RE2), watchdog timer, DTC, CRC calculator, and voltage detection with three selectable thresholds - all in a 64-pin LQFP package with 59 CMOS I/Os and high-current drive capability.
Technical Context
The R5F2136CSNFP#30 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte address space, and a dedicated 16×16→32-bit multiplier with MAC support. Its memory architecture separates program ROM (128 KB), data flash (4 KB BGO-enabled), and RAM (10 KB), with SFRs mapped across 00000h–02FFFh and 06800h–06FFFh for peripheral control including ELC and TSCU.
Peripheral integration includes dual UART interfaces (UART0_0/0_1 and UART2 with I²C mode), one SSU/I²C channel, hardware LIN using UART0_0/0_1 or RJ_0, 10-bit A/D with sweep mode and sample-and-hold, two comparator B circuits, and a 28-channel touch sensor control unit with CHxA0–CHxC and CH00–CH35 dedicated pins - all synchronized via event link controller (30 sources × 10 operations) independent of interrupt handling.

FAQ
What is the maximum operating frequency and voltage range for the R5F2136CSNFP#30?
The R5F2136CSNFP#30 supports a maximum CPU clock of 20 MHz at VCC = 2.7 V to 5.5 V, and operates down to 5 MHz at VCC = 1.8 V to 5.5 V. This dual-voltage flexibility allows deployment in both standard 5 V and low-power 3.3 V or 1.8 V systems while maintaining full peripheral functionality - critical for battery-powered R5F2136CSNFP#30 designs.
Does the R5F2136CSNFP#30 support hardware LIN communication?
Yes, the R5F2136CSNFP#30 integrates a dedicated HW-LIN_0 module compliant with LIN 2.x standards. It uses UART0_0, UART0_1, or Timer RJ_0 resources to implement physical layer timing and protocol handling - reducing CPU overhead by up to 70% compared to software LIN stacks. This makes R5F2136CSNFP#30 ideal for appliance sub-systems requiring deterministic, low-cost bus communication.
How many touch sensing channels does the R5F2136CSNFP#30 support, and what is the implementation method?
The R5F2136CSNFP#30 supports 28 electrostatic capacitive touch channels via its integrated Touch Sensor Control Unit (TSCU), using dedicated pins CHxA0, CHxA1, CHxB, CHxC, and CH00–CH35. It measures floating capacitance changes without external components, delivering noise-immune button/slider detection - a key differentiator for R5F2136CSNFP#30 in modern appliance UIs replacing mechanical switches.
What is the purpose of the Background Operation (BGO) function in the R5F2136CSNFP#30's data flash?
The BGO function allows the R5F2136CSNFP#30 to execute program code from flash memory while simultaneously erasing or writing to data flash blocks (1 KB × 4). This enables seamless firmware updates, parameter logging, or calibration storage without halting real-time tasks - a critical capability for R5F2136CSNFP#30 in always-on consumer devices requiring zero-downtime field upgrades.
Which serial interfaces are available on the R5F2136CSNFP#30, and how are they allocated?
The R5F2136CSNFP#30 provides UART0 (two independent channels), UART2 (supporting clock-synchronous/asynchronous modes plus I²C-bus and LIN), and SSU/I²C (one channel shared between synchronous serial and I²C protocols). Pin multiplexing is documented in Tables 1.4–1.6 of the datasheet, allowing flexible interface assignment - essential for R5F2136CSNFP#30 designs integrating Bluetooth modules, touch controllers, and sensor networks.
