Description
RL78/G1A microcontrollers balance the industry"s lowest level of consumption current (CPU: 66 µA/MHz, standby (STOP): 230 nA) and a high performance of 41 DMIPS (32 MHz). A built-in high-resolution 12-bit A/D converter, on-chip oscillator, data flash, and safety features (function that detects illegal operation of hardware) enable support for the household appliance safety standard (IEC/UL 60730). With an lineup of 25 to 64-pin LGA/BGA and other small packages, these microcontrollers are perfect for consumer and industrial sensor applications.
- Minimum instruction execution time can be changed from high speed (0.03125 s: @ 32 MHz operation with high speed on-chip oscillator clock) to ultra low-speed (30.5 s: @ 32.768 kHz operation with subsystem clock)
- General-purpose register: 8 bits x 32 registers (8 bits x 8 registers x 4 banks)
- ROM: 24 to 512 KB, RAM: 2 to 24 KB, Data flash memory: 8 KB
- On-chip high-speed on-chip oscillator clocks
- Select from 32 MHz (TYP.), 24 MHz (TYP.), 16 MHz (TYP.), 8 MHz (TYP.), and 4 MHz (TYP.)
- On-chip single-power-supply flash memory (with prohibition of block erase/writing function)
- Self-programming (with boot swap function/flash shield window function)
- On-chip debug function
- On-chip power-on-reset (POR) circuit and voltage detector (LVD)
- On-chip watchdog timer (operable with the dedicated low-speed on-chip oscillator clock)
