ATMEGA16A-PU Description

Short technical summary and product information.

The Microchip ATMEGA16A-PU is an 8-bit AVR microcontroller based on the advanced RISC architecture. It offers 16 KB of in-system self-programmable Flash memory, 1 KB of SRAM, and 512 bytes of EEPROM. The device operates at up to 16 MHz, delivering up to 16 MIPS throughput.

 

This microcontroller includes a rich set of peripherals: 32 general-purpose I/O lines, 8-channel 10-bit ADC, 4 PWM channels, three flexible timer/counters, and a programmable watchdog timer. Communication interfaces include I²C, SPI, and UART/USART. It also features a JTAG interface for boundary-scan and on-chip debug.

 

The ATMEGA16A-PU is housed in a 40-pin DIP (0.600 inch width) package for through-hole mounting. It supports a supply voltage range of 2.7V to 5.5V and operates over an industrial temperature range of -40°C to +85°C. The device is RoHS compliant and lead-free.
