FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100ACDSP#X0?
The R5F100ACDSP#X0 operates at up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over VDD = 1.8–5.5 V, TA = –20 to +85°C). At this speed, active current is 66 μA per MHz - meaning total active current is approximately 2.1 mA at 32 MHz. In STOP mode with RTC and LVD active, current drops to 0.57 μA, enabling multi-year battery life in intermittent-sensing applications.
Does the R5F100ACDSP#X0 support in-system programming and secure flash protection?
Yes, the R5F100ACDSP#X0 supports full in-system programming via on-chip debug interface, including boot swap functionality and flash shield window for region-based write protection. The security function prohibits block erase and rewriting of protected flash sections, preventing unauthorized firmware modification while allowing safe field updates to designated areas.
What are the analog capabilities of the R5F100ACDSP#X0, and how is the ADC referenced?
The R5F100ACDSP#X0 features a 10-bit successive-approximation ADC with 6 input channels (ANI0–ANI5). It supports internal 1.45 V reference voltage and an integrated temperature sensor (usable only in HS mode). AVREFP and AVREFM pins allow external reference configuration, and the ADC operates across the full 1.6–5.5 V VDD range - enabling direct measurement of sensors powered from the same rail.
Can the R5F100ACDSP#X0 drive standard 5 V logic peripherals despite its 1.6–5.5 V supply range?
No - the R5F100ACDSP#X0 I/O pins are not 5 V tolerant. Its GPIO operates at VDD level (1.6–5.5 V), and absolute maximum rating for input voltage is VDD + 0.3 V. To interface with 5 V peripherals, level-shifting circuitry (e.g., TXB0104 or discrete MOSFET translators) is required. However, its "different potential interface" feature simplifies connection to 1.8 V, 2.5 V, or 3 V devices without external translation.
What debug and development tools are officially supported for the R5F100ACDSP#X0?
Renesas provides full toolchain support for the R5F100ACDSP#X0, including CS+ IDE with compiler and debugger, E2 emulator Lite for on-chip debugging and flash programming, and the Renesas Flash Programmer for production programming. The device's on-chip debug interface requires only four pins (VDD, VSS, RESET, and TOOLx), eliminating need for JTAG adapters in most development workflows.
