RA0 microcontrollers from Renesas are low-cost gadgets that provide low energy consumption and a characteristic set optimized for cost-sensitive purposes. The MCUs can be utilized in such purposes as shopper electronics, system management for small home equipment, constructing automation, and industrial management programs.
Based mostly on an Arm Cortex-M23 core, the 32-bit MCUs eat 84.3 µA/MHz in energetic mode, dropping to simply 0.82 mA in sleep mode. A software program standby mode cuts present consumption even additional, permitting the system to sip simply 0.2 µA. These options, coupled with a high-speed on-chip oscillator for quick wakeup, make the MCUs notably well-suited for battery-operated merchandise.
The primary gadgets within the RA0 collection, the RA0E1 group, function from a provide voltage of 1.6 V to five.5 V. This implies there isn’t a want for a degree shifter/regulator in 5-V programs. An on-chip oscillator improves baud price accuracy and maintains ±1.0% precision over a temperature vary of -40°C to +105°C.

Different options of the RA0E1 group of MCUs embrace:
Reminiscence: As much as 64 kbytes of code flash and 12 kbytes of SRAM
Analog Peripherals: 12-bit ADC, temperature sensor, inside reference voltage
Communications Peripherals: 3 UARTs, 1 Async UART, 3 Simplified SPIs, 1 IIC, 3 Simplified IICs
Security: SRAM parity test, invalid reminiscence entry detection, frequency detection, A/D take a look at, immutable storage, CRC calculator, register write safety
Safety: Distinctive ID, TRNG, flash learn safety
RA0E1 microcontrollers are transport now. Bundle choices embrace 20-pin LSSOP, 32-pin LQFP, and QFN with 16, 24, or 32 leads.
