Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Figure 1 shows how only one pin—PA0—of the microcontroller is used to implement the different functions for the battery-monitor (BattMon) circuit, driving switch S from Idle to Active mode ...

The 6-pin, SOT-23 PIC10F204 microcontroller fits this description very well. The PIC10F204 has an internal comparator, so we will not require an external comparator.

Atmel has introduced a 6-pin microcontroller. The 8bit AVR ATtiny10 has 1kbyte of flash and 32byte of SRAM in a 2x3mm SOT-23 package. Performance is claimed to be up to 12MIPS, and peripherals include ...
