Product details
Overview
R5F1008CALA#U0 from Renesas is a 25-pin WFLGA-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes, integrated RTC, 10-bit ADC (6 channels), and UART/I²C/CSI interfaces - deployed in battery-powered sensor nodes and industrial control panels.
For engineers reviewing the R5F1008CALA#U0 datasheet, R5F1008CALA#U0 pinout, R5F1008CALA#U0 application, or R5F1008CALA#U0 equivalent, key selection criteria include its 25-pin WFLGA-0.5 mm pitch package, -40°C to +85°C industrial-grade temperature range (A-grade), 0.57 μA RTC+LVD standby current, and support for background data flash rewriting during program execution.
Technical Context
The R5F1008CALA#U0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and a dedicated low-speed on-chip oscillator for watchdog timer operation.
Its peripheral set includes one 12-bit interval timer, one real-time clock with calendar/alarm/correction functions, eight 16-bit timers, three I²C/Simplified I²C channels, two UART/LIN channels, two CSI channels, and an 8/10-bit ADC with internal 1.45 V reference and temperature sensor - all configurable via register-based control without external timing components.

FAQ
What is the maximum operating frequency and associated performance of the R5F1008CALA#U0?
The R5F1008CALA#U0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This is achieved using the high-accuracy ±1.0% on-chip oscillator across 1.8–5.5 V and -40°C to +85°C. Its RL78 CPU core executes instructions in as little as 0.03125 μs in high-speed mode, enabling responsive real-time control in the R5F1008CALA#U0 without external clock sources.
Does the R5F1008CALA#U0 support in-system programming and secure firmware updates?
Yes, the R5F1008CALA#U0 supports self-programming with boot swap functionality and flash shield window protection. It allows safe firmware updates via background operation (BGO) on its 4 KB data flash, and includes security features like block erase prohibition. These capabilities ensure robust, field-upgradable firmware integrity in the R5F1008CALA#U0 without requiring external programmers during deployment.
What analog features are integrated into the R5F1008CALA#U0?
The R5F1008CALA#U0 integrates a 10-bit ADC with six analog input channels, internal 1.45 V reference voltage, and a calibrated on-die temperature sensor. The ADC operates across the full 1.6–5.5 V supply range and supports simultaneous sampling configurations. These analog resources eliminate external components in the R5F1008CALA#U0 for sensor interfacing, supply monitoring, and thermal management.
How does the R5F1008CALA#U0 achieve ultra-low-power operation in battery-powered applications?
The R5F1008CALA#U0 achieves ultra-low-power operation through multiple hardware-optimized states: HALT mode (66 μA/MHz), STOP mode (0.57 μA with RTC + LVD), and SNOOZE mode for peripheral-triggered wake-up. Its low-voltage operation (1.6 V minimum) and on-chip LVD with 14 threshold levels enable precise brown-out detection - extending operational life in the R5F1008CALA#U0 for coin-cell or energy-harvesting systems.
What communication interfaces are available on the R5F1008CALA#U0 and how are they configured?
The R5F1008CALA#U0 provides two UART/LIN channels, three I²C/Simplified I²C channels, and two CSI (SPI-compatible) channels - all configurable via dedicated peripheral registers. Pins are multiplexed (e.g., P10–P13 support SCK00/SI00/SO00/SS00), and interface mode is selected at runtime. No external transceivers are needed for LIN physical layer compliance, and I²C supports standard/fast-mode speeds - maximizing flexibility in the R5F1008CALA#U0's system integration.
