Overview
R5F2136ACNFP#V0 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 96 KB flash program ROM, 8 KB data flash (4 × 1 KB blocks with background operation), and 8 KB RAM. It operates at up to 20 MHz (50 ns min instruction time) on 2.7–5.5 V supply, integrates 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and six independent timers including complementary PWM-capable Timer RD - used in motor control subsystems of home appliance mainboards.
For engineers reviewing the R5F2136ACNFP#V0 datasheet, R5F2136ACNFP#V0 pinout, R5F2136ACNFP#V0 application, or R5F2136ACNFP#V0 equivalent, key selection considerations include its 64-pin LQFP (PLQP0064KB-A) package, −20°C to +85°C industrial temperature grade, integrated voltage detection with programmable reset levels, and BGO-enabled data flash for firmware updates without halting execution.
Technical Context
The R5F2136ACNFP#V0 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte linear address space, and hardware 16×16→32-bit multiplier with MAC support. Its memory architecture separates program ROM (04000h–1BFFFh), data flash (03000h–03FFFh), and RAM (00400h–023FFh), enabling concurrent code execution and data flash reprogramming via BGO.
Peripheral integration includes three UART channels (UART0/1/2), I²C bus (shared with SSU), LIN 2.0-compliant module using UART0 and Timer RA, 14-bit watchdog timer with low-speed on-chip oscillator option, and DTC supporting 39 activation sources across normal and repeat transfer modes.
