FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104PKGFA#30?
The R5F104PKGFA#30 operates at up to 32 MHz and delivers 44 DMIPS performance. This metric reflects its real-world instruction throughput under typical compiler-optimized code, enabling fast execution of control algorithms, communication stacks, and sensor processing routines without requiring external acceleration.
Does the R5F104PKGFA#30 support LIN bus communication, and how is it implemented?
Yes, the R5F104PKGFA#30 supports LIN bus communication through its UART peripheral with built-in LIN protocol features including automatic sync field detection, checksum calculation, and break signal generation. No external LIN transceiver is needed for basic slave-node functionality, reducing BOM cost and board area.
What are the memory resources allocated to the R5F104PKGFA#30, and how is data flash utilized in firmware design?
The R5F104PKGFA#30 includes 96 KB of code flash memory and 8 KB of data flash memory. The data flash supports background operation (BGO), allowing the CPU to execute application code from program memory while rewriting non-volatile parameters - essential for field-upgradable calibration tables and configuration storage in R5F104PKGFA#30-based systems.
How does the R5F104PKGFA#30 achieve ultra-low power consumption, and what are the key low-power modes?
The R5F104PKGFA#30 achieves ultra-low power via HALT (66 μA/MHz), STOP (0.60 μA), and SNOOZE modes. STOP mode retains RTC and LVD operation while disabling CPU and most peripherals - ideal for battery-powered devices requiring periodic wake-up. All modes are entered via software control with fast wake-up latency (< 4 µs from HALT).
What analog peripherals are integrated into the R5F104PKGFA#30, and are external references required?
The R5F104PKGFA#30 integrates a 10-bit, 20-channel ADC with selectable internal 1.45 V reference voltage and AVREFP/AVREFM pins for external reference use. It also includes an 8-bit D/A converter, two comparators with window mode, and an on-chip temperature sensor - eliminating need for external references in most precision sensing applications.
