Product details
Overview
R5F10RBCAFP#V0 from Renesas is a 32-pin LQFP 16 KB flash RL78/L12 16-bit microcontroller with integrated LCD controller/driver, 2 KB data flash, 1 KB RAM, and ultra-low-power operation (62.5 μA/MHz active, 0.64 μA in RTC+LVD halt mode), designed for battery-powered LCD display applications such as smart meters and portable medical devices.
For engineers reviewing the R5F10RBCAFP#V0 datasheet, R5F10RBCAFP#V0 pinout, R5F10RBCAFP#V0 application, or R5F10RBCAFP#V0 equivalent, key selection criteria include its 32-pin LQFP-0.8 mm pitch package, 16 KB code flash with self-programming, on-chip 24 MHz ±1% oscillator, 10-bit ADC with internal 1.45 V reference, and support for capacitor-split LCD drive up to 35 seg × 4 com.
Technical Context
The R5F10RBCAFP#V0 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 clock cycles. It integrates a dedicated LCD controller supporting waveform types A/B, 16-step contrast adjustment, and blinking control - all configurable without CPU intervention.
Its power management includes POR, 14-level LVD with interrupt/reset options, and multiple low-power modes (Stop, Halt, Snooze). The peripheral set includes UART, I²C, two CSI interfaces (SPI-compatible), 8-channel 16-bit timer array, RTC with calendar/alarm, and DMA with background data flash operations.

FAQ
What is the maximum operating frequency and power consumption of the R5F10RBCAFP#V0?
The R5F10RBCAFP#V0 operates at up to 24 MHz using its on-chip high-speed oscillator, delivering 31 DMIPS. In active mode, it consumes 62.5 μA per MHz at 1.8–5.5 V. In Halt mode with only RTC and LVD enabled, current drops to 0.64 μA - verified in the R01DS0157EJ0223 datasheet Section 1.1.
Does the R5F10RBCAFP#V0 support external crystal oscillators?
Yes, the R5F10RBCAFP#V0 supports external crystals on X1/P121 and X2/P122 pins for main system clock operation, as well as XT1/P123 and XT2/P124 for subsystem clock (32.768 kHz). These are fully documented in the Pin Configuration section (Page 6) and Block Diagram (Page 13) of the R01DS0157EJ0223 datasheet.
How many LCD segments and commons does the R5F10RBCAFP#V0 support?
The R5F10RBCAFP#V0 supports up to 35 segment × 8 common or 39 segment × 4 common LCD configurations, implemented via its integrated LCD controller/driver. This is confirmed in Section 1.1 (Features) and Table 1-1 (Page 4) of the R01DS0157EJ0223 datasheet, specifying "35 seg x 8 com or 39 seg x 4 com" capability.
What is the data flash endurance specification for the R5F10RBCAFP#V0?
The R5F10RBCAFP#V0 includes 2 KB of data flash memory rated for 1 million erase cycles (typical), with erase/programming voltage supported from 1.8 V to 5.5 V. This specification is explicitly stated in the "Data Flash Memory" subsection of Section 1.1 (Page 1) of the R01DS0157EJ0223 datasheet.
Is the R5F10RBCAFP#V0 pin-compatible with other RL78/L12 variants?
No - the R5F10RBCAFP#V0 is a 32-pin LQFP device, while other RL78/L12 variants use 44-, 48-, 52-, or 64-pin packages. Pin compatibility is limited to same-pin-count variants (e.g., R5F10RB8AFP#V0 and R5F10RBAAFP#V0), as confirmed in Table 1-1 (Pages 4–5) of the R01DS0157EJ0223 datasheet.
