Overview
The AVR64DB48-E/PT is an 8-bit microcontroller from the AVR DB family, featuring a hardware multiplier CPU running at up to 24 MHz. It includes 64 KB of Flash memory, 8 KB of SRAM, and 512 bytes of EEPROM. The device operates within a supply voltage range of 1.8V to 5.5V and supports an extended temperature range of -40°C to +125°C. It is housed in a 48-pin TQFP package.
Feature Summary
- Features Multi-Voltage I/O (MVIO) on Port C for flexible interface compatibility.
- Includes analog subsystems with three op amps, three zero-cross detectors, and a 12-bit differential ADC.
- Supports CPU-independent inter-peripheral signaling via the Event System.
- Provides Configurable Custom Logic (CCL) with programmable Look-up Tables.
Applications
- Industrial control systems requiring robust analog signal conditioning
- Power control applications utilizing optimized PWM timers and zero-cross detection
- Multi-voltage embedded interfaces using MVIO capabilities
Procurement Notes
Verify that the ordering suffix 'E' corresponds to the extended temperature range (-40°C to +125°C) and '/PT' indicates the 48-pin TQFP package. Confirm RoHS3 compliance and REACH status requirements against specific project standards before finalizing procurement orders.
Selection Notes
Select this component when vertical migration within the AVR DB family is required without code modification. Choose this part if the application demands extended temperature operation or requires multi-voltage I/O support on specific ports compared to industrial grade variants.
Part Context
This device belongs to the AVR64DB28/32/48/64 series, which shares pin and feature compatibility for easy vertical migration. The 'AVR64DB48' designation indicates 64 KB Flash and 48 pins, while '-E' specifies the extended temperature rating and '/PT' denotes the TQFP package style.
Replacement Considerations
AVR64DB48-I/PT serves as the industrial temperature variant replacement. Other family members like AVR128DB48 offer increased memory but maintain pin compatibility.
