The document introduces a high-performance, low-power AVR® 8-bit microcontroller with advanced RISC architecture, including 130 powerful instructions, most of which can be executed in a single clock cycle. It has 32 8-bit general-purpose working registers, fully static operation, and a throughput of up to 16 MIPS at 16 MHz. In addition, the microcontroller has non-volatile program and data memories, including 16KB of in-system self-programmable flash, 512 bytes of EEPROM, 1KB of internal SRAM, etc. It also features a JTAG interface, 4x25 segment LCD driver, multiple timer/counters, PWM channels, ADC, serial USART, SPI interface, universal serial interface, and more.
The ATmega169P is a low‑power 8‑bit CMOS microcontroller based on Atmel's AVR enhanced RISC architecture. It offers 16 KB of In‑System Self‑Programmable Flash, 512 B EEPROM, 1 KB SRAM, and up to 53 programmable I/O lines. The device includes a rich peripheral set such as three timer/counters, an 8‑channel 10‑bit ADC, a USART, SPI, JTAG, and an on‑chip LCD controller.
Designed for automotive applications, the ATmega169P meets ISO‑TS‑16949 and AEC‑Q100 grade 3 quality standards. It operates from 2.7 V to 5.5 V with speed grades of 0‑8 MHz (2.7‑5.5 V) or 0‑16 MHz (4.5‑5.5 V) and functions across a temperature range of –40 °C to 85 °C. Power‑saving modes reduce consumption to sub‑µA levels, making it suitable for battery‑operated designs.
