Product details
Overview
R5F10WLAGFB#10 from Renesas is a 64-pin, industrial-grade RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 128 KB flash, 8 KB RAM, and 4 KB data flash. It operates from 1.6 V to 5.5 V, delivers 31 DMIPS at 24 MHz, and achieves ultra-low power consumption (71 μA/MHz active, 0.61 μA in RTC+LVD STOP mode), targeting battery-powered LCD display systems in smart meters and industrial HMI panels.
For engineers reviewing the R5F10WLAGFB#10 datasheet, R5F10WLAGFB#10 pinout, R5F10WLAGFB#10 application, or R5F10WLAGFB#10 equivalent, key selection criteria include its 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch) package, dual-voltage LCD drive capability (internal boost/capacitor split/external resistor division), 12-channel 8/10-bit ADC, and support for LIN-bus UART, I²C, and CSI interfaces in resource-constrained embedded designs.
Technical Context
The R5F10WLAGFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 µs min @ 24 MHz HS oscillator). Its memory subsystem includes 128 KB code flash (1 KB block size, security-protected erase), 4 KB background-operable data flash (1M rewrite cycles), and 8 KB on-chip RAM - optimized for real-time firmware execution and nonvolatile parameter storage in field-deployed devices.
Peripherals are tightly integrated for LCD-centric control: 36-segment/4-common LCD driver with selectable voltage methods, dual comparators with internal/external reference inputs, 8-channel 16-bit timer array (including PWM and remote control output), RTC2 with calendar/alarm, and 3 UART channels (one LIN-capable), all operating across –40°C to +105°C with on-chip POR/LVD reset and watchdog supervision.
