Product details

Overview

R5F2LA64ANFP#U0 from Renesas is a 16-bit R8C/LA6A Group microcontroller featuring the R8C CPU core, 16 KB program flash, 2 KB RAM, and 2 KB data flash. It delivers 50 ns minimum instruction execution at 20 MHz (V_CC = 2.7–5.5 V), integrates an on-chip 16×16→32-bit multiplier, and supports real-time clock (Timer RH), 8-channel 10-bit A/D converter, and LCD drive control (max 4 common / 32 segment outputs). It targets embedded control in household appliances with low EMI/EMS design.

For engineers reviewing the R5F2LA64ANFP#U0 datasheet, R5F2LA64ANFP#U0 pinout, R5F2LA64ANFP#U0 application, or R5F2LA64ANFP#U0 equivalent, key selection criteria include its 64-pin LQFP package (0.5 mm pitch), N-grade temperature range (−20 to +85°C), integrated voltage detection and watchdog timer, and support for UART0, I²C-bus, and SSU serial interfaces.

Technical Context

The R5F2LA64ANFP#U0 implements the R8C CPU core with 89 fundamental instructions and operates across a 1 Mbyte address space. Its system clock generation includes four independent circuits: XIN oscillator (up to 20 MHz), dedicated XCIN/XCOUT 32 kHz crystal interface, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - enabling flexible power-mode transitions including wait, stop, and multiple power-off modes.

Peripheral integration centers on deterministic timing and mixed-signal capability: Timer RB0/RB1 (8-bit ×2 with PWM), Timer RC (16-bit with 4 capture/compare registers), Timer RH (real-time clock with calendar functions), and Timer RJ0/RJ1 (16-bit ×2 for pulse width/period measurement and event counting). The device provides 56 programmable CMOS I/O ports, 8 high-current drive pins, and dual comparator B circuits.

FAQ

What is the maximum operating frequency and corresponding supply voltage for R5F2LA64ANFP#U0?

The R5F2LA64ANFP#U0 supports a maximum operating frequency of 20 MHz at V_CC = 2.7–5.5 V. At lower supply voltages (1.8–5.5 V), the maximum frequency is reduced to 8 MHz. This dual-voltage/frequency specification allows flexible power optimization across battery-operated and line-powered designs without changing the R5F2LA64ANFP#U0 part number.

Does R5F2LA64ANFP#U0 include an integrated temperature sensor, and what is its accuracy range?

Yes, the R5F2LA64ANFP#U0 includes an on-chip temperature sensor with a measurement range of −20 to +85°C for the N-version. Accuracy is specified per Renesas datasheet R01DS0011EJ0101 and requires calibration against known references; it is intended for relative thermal monitoring (e.g., overtemperature warning) rather than metrology-grade measurement.

Can R5F2LA64ANFP#U0 operate in low-power modes while maintaining real-time clock functionality?

Yes, the R5F2LA64ANFP#U0 maintains Timer RH real-time clock operation in stop mode and power-off modes (0 and 2) when powered by V_CC and using the dedicated 32 kHz XCIN/XCOUT crystal oscillator. In power-off mode 2 with Timer RH enabled, typical current consumption is 1.3 µA at 3.0 V - enabling multi-year battery backup for calendar functions.

What serial communication interfaces are supported by R5F2LA64ANFP#U0?

The R5F2LA64ANFP#U0 supports UART0 (1 channel), I²C-bus (1 channel, shared with SSU), and synchronous serial I/O (SSU, 1 channel). UART2 is not present in the R8C/LA6A Group - only R8C/LA8A includes UART2. All three interfaces share pins and are software-configurable, allowing flexible peripheral assignment without hardware changes.

Is R5F2LA64ANFP#U0 pin-compatible with other members of the R8C/LA6A Group?

Yes, all R8C/LA6A Group devices in the 64-pin LQFP package (PLQP0064KB-A or PLQP0064GA-A) share identical pinouts, including R5F2LA64ANFP#U0, R5F2LA66ANFP, and R5F2LA68ANFP. Memory size, data flash configuration, and temperature grade vary by part number, but I/O mapping, peripheral pin assignments, and electrical characteristics remain consistent across the group.
