Product details
Overview
R5F2L38CCNFP#30 from Renesas Electronics is a 16-bit R8C/L38C Group single-chip microcontroller featuring the R8C CPU core, 128 KB flash program memory, 10 KB RAM, and integrated LCD drive control supporting up to 48 segment outputs and 8 common outputs. It delivers 50 ns minimum instruction execution at 20 MHz, includes a 16×16-bit hardware multiplier, and targets embedded control in resource-constrained consumer appliances with integrated analog and timing peripherals.
For engineers reviewing the R5F2L38CCNFP#30 datasheet, R5F2L38CCNFP#30 pinout, R5F2L38CCNFP#30 application, or R5F2L38CCNFP#30 equivalent, key selection criteria include its 80-pin LQFP package, 16-channel 10-bit ADC, dual 8-bit D/A converters, real-time clock (Timer RE), and hardware LIN interface-critical for appliance UI and motor control subsystems requiring low EMI and background data flash rewrite capability.
Technical Context
The R5F2L38CCNFP#30 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its system clock generation supports four independent sources: external XIN (up to 20 MHz), 32 kHz XCIN, high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator-enabling flexible power-mode transitions between standard, wait, stop, and power-off modes.
Peripheral integration includes Timer RD (16-bit ×2 with 6-pin PWM, complementary PWM, and reset-synchronous three-phase output), Timer RC (16-bit with 3-pin PWM), and UART0/UART1/UART2 with I²C-bus mode and LIN hardware support. The device also integrates a Data Transfer Controller (DTC) with 38 activation sources and two transfer modes for autonomous peripheral-to-memory transfers.
