ATMEGA164P-A15AZ - 8-bit AVR MCU 16KB Flash, Automotive | Atmel

The Atmel (Microchip Technology) ATMEGA164P-A15AZ is an 8-bit AVR RISC microcontroller with 16 KB of in-system programmable Flash memory, 512 B EEPROM, and 1 KB SRAM, housed in a 44-pin automotive-grade TQFP package (14 x 14 mm, 1 mm height) with gull-wing terminals and a 2.7 V to 5.5 V supply range. An 8-bit AVR microcontroller is a Harvard-architecture processor that executes most of its 133 powerful instructions in a single clock cycle. In the embedded-systems hierarchy, the MCU sits above discrete logic and below application processors, integrating CPU, program memory, data memory, timers, UART, SPI, TWI (I2C) and analog peripherals on a single die. The AVR family is widely used for cost-sensitive control tasks where a full ARM device would be over-specified. Key features of this part include the picoPower AVR core for low active and sleep current, read-while-write Flash for self-programming and bootloaders, 32 general purpose I/O lines, 32 general purpose working registers, and an advanced RISC architecture with single-cycle execution. The -A15AZ suffix denotes the automotive temperature grade, making it suitable for harsh environments beyond commercial ratings. Technically, the device pairs the enhanced AVR core with two 8-bit timers, one 16-bit timer, a 10-bit ADC, USART, SPI, and TWI interfaces. In-circuit debugging and In-Circuit Serial Programming (ICSP) are supported through the SPI pins using tools such as the MPLAB SNAP, per the Microchip product page, enabling field firmware updates without socketed parts. Typical applications include automotive body modules and sensor nodes, industrial control panels, motor control auxiliary logic, and battery-powered instrumentation where the 2.7 V to 5.5 V rail tolerance simplifies power design across 3.3 V and 5 V systems. When designing with the ATMEGA164P-A15AZ, decouple both VCC pin pairs and program fuse bits carefully - wrong fuse settings on an AVR can lock out ISP access. Verify the 8 MHz clock speed grade against your timing budget before pin-migrating from 16 MHz parts.

The PV suffix denotes a wide 1.8V to 5.5V operating voltage, enabling direct operation from two alkaline cells or a 5V industrial rail without a regulator. Architecturally, the ATmega164PV pairs a fully static AVR core with read-while-write Flash, so firmware can update EEPROM or program the Flash while executing, supporting field upgrades and data logging. It also includes a real-time counter with separate oscillator, a JTAG interface for on-chip debugging, and brown-out reset and watchdog timer for robust operation in noisy environments. Typical applications include battery-powered sensor nodes and data loggers exploiting picoPower sleep modes, industrial control panels and HMI boards using the dual USARTs and extended temperature rating, and consumer or metering products using the 10-bit ADC and PWM outputs. The 10 MHz speed grade suits cost- and EMI-sensitive designs that do not require the 20 MHz capability of the ATmega164PA. A key design consideration is clock selection: the 10 MHz maximum frequency is typically achieved from an 8 MHz internal RC oscillator with CKDIV8 fuse disabled plus system clock prescaler, or an external crystal.
