R7F0C908B2DFP-C#BA0 Renesas RL78/F13 16-bit Low-Power MCU 48KB Flash 24MHz LQFP-32
R7F0C908B2DFP-C#BA0 Product Overview
The Renesas R7F0C908B2DFP-C#BA0 from the RL78/F13 series.The device features a 16-bit RL78 CISC core (3-stage pipeline Harvard architecture) running at up to 24MHz with 31 DMIPS performance. Its ultra-low-power platform consumes only 66μA per MHz in run mode, down to 0.23μA in STOP mode (RAM retained), and just 0.70mA in SNOOZE mode (UART). Operating from 1.6V to 5.5V, it offers 48KB code flash, 4KB SRAM, and 4KB data flash (1,000,000 rewrite cycles). Peripherals include up to 8-channel 10-bit ADC (2.1μs conversion), multi-function 16-bit timers (up to 8 channels), 15kHz watchdog timer with window function, and up to 3× simple I²C, 3× CSI/SPI, and 3× UART interfaces. Safety features compliant with IEC/UL 60730 include flash CRC, RAM parity error detection, and illegal memory access detection. I/O ports support 5V tolerance and high current (20mA max per port), in a LQFP-32(7×7mm) package rated for -40℃ to +85℃.
