Renesas R5F1007CANA#W0

Overview

R5F1007CANA#W0 from Renesas is a 24-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 32 KB flash, 2 KB RAM, and 4 KB data flash, operating from 1.6–5.5 V at -40°C to +85°C. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (6 channels), RTC, UART, I²C, CSI, and 16-bit timers for embedded control in space-constrained industrial and consumer devices.

For engineers reviewing the R5F1007CANA#W0 datasheet, R5F1007CANA#W0 pinout, R5F1007CANA#W0 application, or R5F1007CANA#W0 equivalent, key selection criteria include its 24-pin HWQFN footprint, integrated data flash with background operation, low-power STOP/HALT/SNOOZE modes, and support for LIN-bus via UART - critical for battery-powered sensor nodes and motor control modules.

Technical Context

The R5F1007CANA#W0 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory architecture includes separate code flash (32 KB), data flash (4 KB), and RAM (2 KB), with self-programming capability and flash shield window security.

Peripherals are tightly coupled to low-power operation: the 10-bit ADC operates across full VDD range (1.6–5.5 V) with internal 1.45 V reference and temperature sensor; real-time clock provides calendar functionality with alarm and correction; and DMA controller supports 2-channel transfers with 2-clock latency between SFR and RAM.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F1007CANA#W0?

The R5F1007CANA#W0 operates up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs at this speed, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time. This dual-speed capability enables adaptive power/performance trade-offs in real-time applications.

Does the R5F1007CANA#W0 support LIN communication, and how is it implemented?

Yes, the R5F1007CANA#W0 supports LIN communication through its UART peripheral, which includes hardware-assisted LIN features such as automatic break detection, sync field generation, and checksum calculation. No external LIN transceiver is required for basic implementation - only a compliant physical layer driver is needed. The UART's LIN mode is fully compatible with LIN 2.2 and supports both master and slave configurations.

What are the data retention and endurance specifications for the on-chip data flash in the R5F1007CANA#W0?

The R5F1007CANA#W0 includes 4 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) with data retention guaranteed for 20 years at 85°C. Rewrites can be performed across the full VDD range (1.8–5.5 V), and background operation (BGO) allows concurrent code execution and data flash programming - essential for robust firmware updates and parameter logging.

Can the R5F1007CANA#W0 operate from a single 1.8 V supply, and what peripherals remain functional?

Yes, the R5F1007CANA#W0 supports operation from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, all core peripherals function: 10-bit ADC (with internal 1.45 V reference), RTC, UART, I²C, CSI, 16-bit timers, and DMA. However, the high-speed on-chip oscillator is limited to ≤8 MHz below 2.7 V; for full 32 MHz operation, VDD ≥ 2.7 V is required per datasheet specifications.

How does the R5F1007CANA#W0 handle reset and power-supply monitoring?

The R5F1007CANA#W0 integrates an on-chip power-on-reset (POR) circuit and a programmable voltage detector (LVD) with 14 selectable threshold levels (1.6–4.2 V). The LVD can generate either interrupt or reset events, enabling flexible brownout response - e.g., save critical data before reset or trigger graceful shutdown. Both POR and LVD are active across the full operating temperature range (-40°C to +85°C).
