Product details
Overview
R5F2LA68ANFA#30 from Renesas Electronics is a 16-bit R8C/LA6A Group microcontroller featuring 64 KB program flash, 1 KB × 2 data flash, 3.5 KB RAM, 56 programmable I/O pins, and integrated LCD drive (up to 32 segment outputs). It operates at up to 20 MHz (VCC = 2.7–5.5 V), supports real-time clock (Timer RH), 10-bit × 8-channel A/D converter, and low-power stop mode (0.5 µA). It targets cost-sensitive, display-integrated embedded control in household appliances and consumer electronics.
For engineers reviewing the R5F2LA68ANFA#30 datasheet, R5F2LA68ANFA#30 pinout, R5F2LA68ANFA#30 application, or R5F2LA68ANFA#30 equivalent, key selection criteria include its 64-pin LQFP-0.8 mm pitch package, N-grade (−20 to +85°C) temperature rating, on-chip debug support, and dual-voltage detection circuit - all critical for appliance mainboard and panel controller designs requiring long-term supply stability and EMI/EMS robustness.
Technical Context
The R5F2LA68ANFA#30 implements the R8C CPU core with 89 fundamental instructions and hardware multiplier (16 × 16 → 32 bits), enabling efficient signal processing and control loop execution. Its memory architecture includes separate program ROM and data flash with 10,000-cycle endurance, supporting field firmware updates without external EEPROM.
Peripheral integration centers on mixed-signal control: Timer RC provides 16-bit PWM with 4 capture/compare registers; Timer RJ (16-bit × 2) enables pulse width/period measurement; UART0 and SSU/I²C share pins for flexible serial communication; and the LCD drive circuit supports static/1/2/1/3 bias with up to 4 common outputs and 32 segment outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | R8C 16-bit core with 89 instructions, 50 ns min instruction time at 20 MHz - enables deterministic real-time control in appliance motor and sensor subsystems. |
| Memory | 64 KB program flash + 1 KB × 2 data flash + 3.5 KB RAM - sufficient for bootloader, application code, and parameter storage in display-based controllers. |
| I/O & Peripherals | 56 CMOS I/O pins (8 high-current), 10-bit × 8-channel A/D, Timer RH (RTC), Timer RJ × 2, UART0, SSU/I²C, LCD drive (32 seg/4 com) - reduces BOM count in white goods UI modules. |
| Power Management | Operating voltage 1.8–5.5 V; current draw: 4.7 mA (5 V/20 MHz), 0.5 µA (stop mode) - supports battery-backed RTC and energy-efficient standby in smart appliances. |
| Package & Temp | 64-pin LQFP (PLQP0064GA-A, 0.8 mm pitch), −20 to +85°C (N version) - compatible with standard SMT assembly and suited for non-automotive indoor environments. |

Pinout & Package
Package: 64-pin LQFP (PLQP0064GA-A), 0.8 mm pitch, exposed pad not specified, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC/AVCC (Pins 12, 48) | Power supply / Analog reference | Primary 1.8–5.5 V supply; AVCC powers A/D and comparator circuits - requires local decoupling for noise-sensitive analog measurements. |
| VSS/AVSS (Pins 11, 47) | Ground / Analog ground | Digital and analog return paths - separation improves ADC SNR; layout must minimize shared impedance between digital and analog sections. |
| XIN / XOUT (Pins 10, 9) | External crystal oscillator input/output | Supports 20 MHz crystal for high-speed operation; internal feedback resistor enables direct connection without external components. |
| XCIN / XCOUT (Pins 6, 7) | 32 kHz sub-clock oscillator input/output | Enables low-power RTC operation during stop mode; dedicated pins ensure timing stability independent of main clock domain. |
