Product details
Overview
ATMEGA64RZAPV-10MU from Microchip Technology (formerly Atmel) is an 8-bit AVR RISC microcontroller designed for embedded control applications requiring high code efficiency, low power, and in-system programmability. It integrates 64 KB Flash, 4 KB SRAM, 2 KB EEPROM, a 10-bit 8-channel ADC with differential gain options, three timer/counters (including one 16-bit with input capture), two USARTs, SPI, TWI, JTAG debug interface, and six sleep modes. It operates up to 10 MHz at 2.7–5.5 V and is commonly used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the ATMEGA64RZAPV-10MU datasheet, ATMEGA64RZAPV-10MU pinout, ATMEGA64RZAPV-10MU application, or ATMEGA64RZAPV-10MU equivalent, key selection considerations include its 44-pin QFN/MLF package, JTAG-enabled on-chip debugging, true read-while-write Flash capability, differential ADC with 1x/10x/200x programmable gain, and support for brown-out detection and calibrated internal RC oscillator.
Technical Context
The ATMEGA64RZAPV-10MU implements the enhanced AVR RISC architecture with 131 single-cycle instructions and 32 general-purpose registers directly connected to the ALU. Its instruction throughput reaches up to 10 MIPS at 10 MHz, enabling deterministic real-time response in time-critical control loops.
It features a fully static core supporting six software-selectable sleep modes-including Power-down (0.1 µA @ 1.8 V), ADC Noise Reduction, and Extended Standby-with independent clock domains for asynchronous timers and the main system oscillator. The JTAG interface provides boundary-scan testing and full on-chip debug access to Flash, EEPROM, fuses, and lock bits.

FAQ
What is the maximum operating frequency of the ATMEGA64RZAPV-10MU?
The ATMEGA64RZAPV-10MU is rated for operation up to 10 MHz across its full supply voltage range of 2.7 V to 5.5 V. This speed grade is confirmed in the official Microchip datasheet (document 2593OS–AVR–02/12), and the device achieves up to 10 MIPS throughput due to its single-cycle RISC architecture. Exceeding 10 MHz may result in unreliable operation unless voltage is increased beyond 5.5 V - which is outside specification.
Does the ATMEGA64RZAPV-10MU support in-system programming (ISP)?
Yes, the ATMEGA64RZAPV-10MU supports in-system programming via its SPI interface and also through the JTAG interface. Both methods allow reprogramming of Flash, EEPROM, fuses, and lock bits without removing the device from the circuit. The JTAG interface additionally enables full on-chip debugging, making ATMEGA64RZAPV-10MU suitable for development and field firmware updates.
What are the key differences between the ATMEGA64RZAPV-10MU and ATMEGA644PV-10PU?
The ATMEGA64RZAPV-10MU and ATMEGA644PV-10PU share identical core architecture, memory sizes, peripherals, and electrical specifications. Their primary difference lies in packaging: ATMEGA64RZAPV-10MU uses a 44-pad QFN/MLF (7×7 mm), while ATMEGA644PV-10PU uses a 40-pin PDIP. The QFN package offers better thermal performance and smaller footprint, but requires reflow assembly - unlike the through-hole PDIP variant.
Can the ATMEGA64RZAPV-10MU operate from a single 3.3 V supply?
Yes, the ATMEGA64RZAPV-10MU operates reliably from a 3.3 V supply within its specified 2.7–5.5 V range. At 3.3 V, it supports up to 10 MHz operation and delivers typical active current of 240 µA per MHz. Its internal calibrated RC oscillator and brown-out detection circuitry remain fully functional at 3.3 V, enabling robust operation in mixed-voltage systems.
Is there a built-in real-time counter (RTC) in the ATMEGA64RZAPV-10MU?
Yes, the ATMEGA64RZAPV-10MU includes a dedicated Real Time Counter (RTC) module - Timer/Counter2 configured in asynchronous mode - that runs independently from the main system clock using a separate 32.768 kHz crystal or external clock source. This allows timekeeping during Power-save and other low-power sleep modes, supporting applications like timestamping, alarm generation, and periodic wake-up without CPU intervention.
