ATMEGA164P-A15AZ — Microchip AEC-Q100 Automotive 8-Bit AVR Microcontroller
ATMEGA164P-A15AZ from Microchip Technology (formerly Atmel) is an AEC-Q100 automotive-qualified, low-power CMOS 8-bit mcu built on the AVR enhanced RISC architecture, featuring 16 KB of in-system programmable Flash with read-while-write capability, 1 KB SRAM, and 512 bytes of EEPROM, delivered in a 44-TQFP surface-mount package. Operating at up to 16 MHz and achieving throughputs approaching 1 MIPS per MHz, the device runs from a 2.7 V to 5.5 V supply over an extended −40 °C to +125 °C automotive temperature range and integrates a rich peripheral set including 32 GPIO, dual USARTs, SPI, TWI (I²C), an 8-channel 10-bit ADC, and six PWM channels.
Highlights / Key Features
● High-performance AVR RISC core executing 131 powerful instructions in a single clock cycle, with 32 x 8 general-purpose working registers directly connected to the ALU for up to 10x the code efficiency of conventional CISC microcontrollers.
● 16 KB ISP Flash with read-while-write self-programming, plus 1 KB SRAM and 512 bytes of EEPROM for program, data, and parameter storage in a single chip.
● AEC-Q100 automotive qualification with a −40 °C to +125 °C operating temperature range and 16 MHz maximum clock over the full 2.7 V to 5.5 V supply span.
● Comprehensive connectivity featuring two byte-oriented USARTs, an SPI serial interface, and a TWI (I²C-compatible) two-wire interface for multi-protocol system communication.
● Rich analog and timing peripherals including an 8-channel 10-bit ADC with differential mode and selectable 1x/10x/200x gain, six PWM channels, one 8-bit timer, one 16-bit timer, and an analog comparator.
● Robust system supervision with internal calibrated oscillator, POR, brown-out detect/reset, programmable watchdog timer, and six flexible sleep modes for power-sensitive automotive nodes.
Applications
The ATMEGA164P-A15AZ MCU is engineered for automotive and industrial embedded control demanding AEC-Q100 reliability and versatile interfacing. Typical applications include automotive body-control modules, window/seat/mirror actuators, lighting control, HVAC blower controllers, dashboard indicators, industrial automation PLCs and motor supervision, battery-powered instrumentation, access-control terminals, white goods, and legacy legacy system maintenance where a proven 16 KB AVR with dual UARTs and 10-bit ADC is required.
Alternative / Replacement Models
● ATMEGA164PA-15AZ — The automotive-grade version of the 164PA retaining AEC-Q100 qualification and the same TQFP-44 footprint for direct legacy substitution.
● ATMEGA324PA-AU — Memory-upgraded sibling with 32 KB Flash and 2 KB SRAM in the same 44-TQFP pinout, ideal when application code outgrows 16 KB.
● ATMEGA644PA-AU — High-memory variant offering 64 KB Flash, 4 KB SRAM, and 2 KB EEPROM at 20 MHz in pin-compatible TQFP-44 for feature-rich upgrades.
● ATMEGA164A-AU — Cost-optimized industrial variant of the same architecture with 16 KB Flash in TQFP-44 for non-automotive applications.
