ATtiny4313 is a RISC-based high-performance low-power 8-bit microcontroller with 4 KB flash memory, 256 Bytes EEPROM, and 256 Bytes SRAM. It has 20 pins and 18 general-purpose I/O lines.
Renesas Electronics has introduced a single-chip solution with touch sensing and voice recognition capabilities for contactless operation to the popular RX Family.
Espressif Systems Co., Ltd. has announced the release of ESP32-H2 with integrated IEEE 802.15.4 radio and Bluetooth 5.2 (LE) connectivity, operable in the 2.4 GHz band.
Infineon Technologies AG has announced the high-density, radiation-tolerant (RadTol) NOR Flash memory products which are qualified to MIL-PRF-38535’s QML-V flow and deliver superior, low-pin count, single-chip solution for applications such as FPGA configuration, image
The Arduino Nano is another popular Arduino development board very much similar to the Arduino UNO. They use the same Processor (Atmega328p) and hence they both can share the same program.
