The R5F21344CDFP#30 supports up to 20 MHz operation at VCC = 2.7–5.5 V, and 5 MHz at VCC = 1.8–5.5 V. Its minimum instruction execution time is 50 ns under the 20 MHz condition, enabling responsive real-time control. The extended 1.8 V lower limit allows compatibility with battery-backed or low-power subsystems without level-shifting.
Does the R5F21344CDFP#30 include hardware support for LIN communication?
Yes, the R5F21344CDFP#30 integrates a dedicated hardware LIN module compliant with LIN 2.1, implemented using Timer RA and UART0. This eliminates the need for external LIN transceivers in basic node applications and ensures deterministic timing for frame transmission and synchronization without CPU overhead.
How many analog-to-digital converter (ADC) channels does the R5F21344CDFP#30 provide, and what is its resolution?
The R5F21344CDFP#30 features a 10-bit resolution ADC with 12 input channels (AN0–AN11), including sample-and-hold functionality and sweep mode for automatic sequential conversion. This enables precise acquisition of multiple sensor signals-such as thermistors, potentiometers, or current shunts-in a single firmware cycle.
What package type and pin count does the R5F21344CDFP#30 use?
The R5F21344CDFP#30 uses a 48-pin LQFP package designated PLQP0048KB-A (formerly 48P6Q-A), with 7 mm × 7 mm body size and 0.5 mm pin pitch. This RoHS-compliant package supports standard reflow soldering and provides sufficient I/O density for mixed-signal control applications without requiring BGA assembly.
Is background operation (BGO) supported for data flash writes on the R5F21344CDFP#30?
Yes, the R5F21344CDFP#30 supports Background Operation (BGO) for its 4 KB data flash (1 KB × 4 blocks), allowing erase and program operations to proceed concurrently with main program execution. This capability is essential for reliable over-the-air firmware updates and nonvolatile parameter storage in mission-critical systems.
