ATSAMA5D27A-CU

Microprocessors Overview

The ATSAMA5D27A-CU is a Microchip Technology microprocessor based on the ARM Cortex-A5 core, operating at a maximum clock frequency of 500 MHz. It features a 32-bit data bus and is housed in a 289-ball LFBGA package measuring 14x14 mm with a 0.8 mm pitch. The device includes 32 kB L1 instruction cache, 32 kB L1 data cache, and 128 kB L2 cache. Internal memory consists of 128 kB SRAM and 160 kB ROM. It supports I/O voltages from 1.65 V to 3.6 V, operates within a temperature range of -40°C to +85°C, and provides 128 I/O lines.

Microprocessors Feature Summary

• Integrates ARM TrustZone technology for hardware-based security, including tamper detection and secure boot capabilities.
• Features a multimedia processing engine (NEON MPE) and floating-point unit for efficient application execution.
• Includes a high-bandwidth multi-port dynamic RAM controller supporting various DDR standards with encryption paths.
• Provides flexible serial communication controllers capable of supporting multiple protocols such as SPI, USART, and TWI.

Microprocessors Applications

• Human Machine Interface (HMI) systems
• White goods and home appliances
• Kiosks and Point of Sale (POS) terminals

Microprocessors Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm RoHS compliance status and check for specific manufacturing site notices via official datasheets. Ensure handling procedures account for moisture sensitivity levels during storage and assembly to maintain device integrity.

Microprocessors Selection Notes

Select this model when a 289-pin BGA footprint is required for SAMA5D2 series integration. It offers higher I/O density compared to smaller packages like the 256-ball variant. Verify that the target design supports the 1.2 V core voltage and 1.65-3.6 V I/O requirements before finalizing the schematic.

Microprocessors Part Context

This component belongs to the SMART SAMA5D2 family of embedded microprocessors designed for Linux-based applications. It shares architectural similarities with other SAMA5D2 variants but is distinguished by its specific pin count and internal memory configuration suitable for complex industrial control tasks.

Microprocessors Replacement Considerations

Direct substitutes include ATSAMA5D27C-CU and ATSAMA5D28A-CU within the same package. Verify pin compatibility and memory specifications against the original design requirements before substitution.
