For engineers reviewing the R5F12048GSP#70 datasheet, R5F12048GSP#70 pinout, R5F12048GSP#70 application, or R5F12048GSP#70 equivalent, key selection criteria include its 16-pin SSOP package, 8 KB code flash with self-programming, high-speed on-chip oscillator accuracy of ±1.0% (−20°C to +85°C), and integrated comparator with internal reference voltage.
Technical Context
The R5F12048GSP#70 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting minimum instruction execution at 0.0625 μs (16 MHz) and address space up to 1 MB. It integrates a selectable power-on-reset circuit with four detection voltage levels and operates from a single 2.4–5.5 V supply.
Its peripheral set includes TAU0 timer array (8 channels), SAU0 serial array unit (2 channels), UART0, IICA0, and CSI00/CSI01 - all configurable via peripheral I/O redirection registers (PIOR). The device supports HALT and STOP low-power modes with 54-μA/MHz typical active current at 125°C.
