Does the R5F21336CDFP#50 support in-system programming of its data flash memory?
Yes, the R5F21336CDFP#50 supports background operation (BGO) for data flash, enabling erase and write operations while the CPU executes code from program ROM. This allows seamless firmware updates, parameter storage, or data logging without halting real-time tasks - a key requirement for field-deployed appliances and industrial controllers.
What peripheral resources does the R5F21336CDFP#50 provide for analog signal conditioning?
The R5F21336CDFP#50 integrates a 10-bit A/D converter with 12 input channels and sample-and-hold, two independent 8-bit D/A converters (DA0/DA1), four comparator B inputs (IVCMP1/IVCMP3, IVREF1/IVREF3), and dedicated VREF input. These resources support closed-loop control, sensor calibration, audio signal generation, and precision analog monitoring without external components.
How is the LIN bus functionality implemented on the R5F21336CDFP#50?
The R5F21336CDFP#50 implements hardware LIN 2.0/2.1 using Timer RA for baud rate generation and pulse timing, combined with UART0 for data framing and error checking. This integrated approach eliminates the need for an external LIN transceiver IC, reducing BOM cost and PCB area in automotive body modules and appliance sub-networks.
What are the low-power modes supported by the R5F21336CDFP#50 and their typical current consumption?
The R5F21336CDFP#50 supports wait mode (3.5 µA at 3.0 V with 32 kHz XCIN clock) and stop mode (2.0 µA at 3.0 V), in addition to standard active operation (6.5 mA at 5.0 V/20 MHz).
