Product details
Overview
ATMEGA64RZAPV-10AU from Microchip Technology (formerly Atmel) is an 8-bit AVR RISC microcontroller designed for embedded control with integrated 64 KB Flash, 4 KB SRAM, and 2 KB EEPROM. It delivers up to 10 MIPS at 10 MHz, supports true Read-While-Write Flash programming, and features a 10-bit 8-channel ADC with differential mode and programmable gain. It is used in industrial sensor nodes requiring low-power operation and in-system reprogrammability.
For engineers reviewing the ATMEGA64RZAPV-10AU datasheet, ATMEGA64RZAPV-10AU pinout, ATMEGA64RZAPV-10AU application, or ATMEGA64RZAPV-10AU equivalent, key selection considerations include its 40-pin TQFP package, JTAG debug interface, six sleep modes, 16-bit Timer/Counter with input capture, and 10-bit ADC performance at 1.8–5.5 V supply range.
Technical Context
The ATMEGA64RZAPV-10AU implements the enhanced AVR RISC architecture with 131 single-cycle instructions and 32 general-purpose registers directly connected to the ALU. Its core executes instructions at up to 10 MIPS at 10 MHz, enabling deterministic real-time response in resource-constrained systems.
It integrates three independent timer/counters (two 8-bit, one 16-bit), a Real Time Counter with dedicated oscillator, and a byte-oriented Two-wire Serial Interface (TWI) compliant with I²C protocol. The device supports IEEE 1149.1 JTAG boundary-scan and on-chip debug, enabling full in-system programming of Flash, EEPROM, fuses, and lock bits without external hardware.

FAQ
What is the maximum operating frequency of the ATMEGA64RZAPV-10AU?
The ATMEGA64RZAPV-10AU is rated for up to 10 MHz operation across its full 2.7–5.5 V supply range. This speed grade is confirmed by Microchip's characterization data and defines the upper limit for instruction execution, peripheral clocking, and ADC sampling rate - exceeding this frequency risks timing violations and undefined behavior.
Does the ATMEGA64RZAPV-10AU support true Read-While-Write Flash operation?
Yes, the ATMEGA64RZAPV-10AU supports true Read-While-Write Flash: application code can execute from one Flash section while another section is being reprogrammed via the boot loader or JTAG interface. This capability is implemented in hardware and enables seamless firmware updates without halting system operation - a key feature verified in the ATmega644 datasheet Section 2.1.
What sleep modes are available on the ATMEGA64RZAPV-10AU and what is the lowest power consumption?
The ATMEGA64RZAPV-10AU offers six software-selectable sleep modes: Idle, ADC Noise Reduction, Power-save, Power-down, Standby, and Extended Standby. In Power-down mode at 1.8 V, it consumes only 0.1 µA - the lowest specified current - making it suitable for battery-powered applications requiring multi-year operation between replacements.
Can the ATMEGA64RZAPV-10AU's ADC perform differential measurements with programmable gain?
Yes, the ATMEGA64RZAPV-10AU's 10-bit ADC supports differential input mode with selectable gains of 1×, 10×, or 200× using internal PGA circuitry. This allows high-resolution measurement of small differential signals (e.g., from bridge sensors) without external amplification - a feature explicitly documented in the "Peripheral Features" section of the ATmega644 datasheet.
Is JTAG debugging supported on the ATMEGA64RZAPV-10AU and what functions does it enable?
Yes, the ATMEGA64RZAPV-10AU includes a full IEEE 1149.1-compliant JTAG interface that enables boundary-scan testing, on-chip debugging, and complete in-system programming of Flash, EEPROM, fuses, and lock bits. This eliminates the need for external programmers during development and supports production programming via standard JTAG adapters - confirmed in the "JTAG (IEEE std. 1149.1 Compliant) Interface" feature list.
