ATSAMA5D28C-D1G-CU Equivalent & Substitute Parts

Part Overview

The ATSAMA5D28C-D1G-CU is an ARM Cortex-A5 microprocessor from Microchip Technology's SAMA5D2 series, operating at 500MHz with integrated multimedia acceleration and comprehensive security features. This single-core, 32-bit processor is designed for embedded applications requiring graphics acceleration, display control, and secure processing capabilities. The part is currently in active production status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when electrical specifications, package compatibility, and functional capabilities remain equivalent across the SAMA5D2 product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the SAMA5D2 microprocessor family is determined by strict equivalence across core electrical and mechanical parameters. The following criteria establish valid substitute relationships:

• Identical ARM Cortex-A5 core architecture and 500MHz clock speed
• Matching 289-LFBGA (14x14) package footprint and pinout
• Equivalent 3.3V I/O voltage specification
• Identical operating temperature range (-40°C ~ 85°C)
• Matching RAM controller support (LPDDR1, LPDDR2, LPDDR3, DDR2, DDR3, DDR3L, QSPI)
• Equivalent peripheral interface set (I2C, SMC, SPI, UART, USART, QSPI)
• Identical security feature implementation (ARM TrustZone, Boot Security, Cryptography, RTIC, Secure Fusebox, Secure JTAG, Secure Memory, Secure RTC)
• Active product status with current manufacturing support
• ROHS3 compliance and REACH unaffected status

Packaging variations (Cut Tape vs. Digi-Reel) do not affect electrical or functional equivalence and represent only distribution format differences.

Parameter Comparison

Engineering Selection Recommendations

Both the ATSAMA5D28C-D1G-CU and ATSAMA5D27C-CUR are functionally equivalent microprocessors within the SAMA5D2 family. Selection between these parts is based on:

• Product availability and inventory status
• Packaging format requirements (Digi-Reel vs. standard packaging)
• Supply chain and procurement lead times
• Both parts maintain active production status with full regulatory compliance (ROHS3, REACH unaffected)
• Identical ECCN and HTSUS classifications ensure equivalent export and import compliance

No electrical or functional differentiation exists between these parts. PCB design, firmware, and system integration remain unchanged when substituting between these microprocessors.

Frequently Asked Questions (FAQ)

Q: Are ATSAMA5D28C-D1G-CU and ATSAMA5D27C-CUR pin-compatible?

A: Yes. Both parts use the 289-LFBGA (14x14) package with identical pinout. Direct substitution on the PCB is possible without layout modifications.

Q: What is the difference between these two part numbers?

A: The parts are electrically and functionally identical. Differences exist only in packaging format and distribution method. ATSAMA5D27C-CUR is supplied in Cut Tape and Digi-Reel format, while ATSAMA5D28C-D1G-CU uses standard packaging.

Q: Can I use ATSAMA5D27C-CUR as a drop-in replacement for ATSAMA5D28C-D1G-CU?

A: Yes. All electrical specifications, performance characteristics, security features, and interface capabilities are identical. No firmware or design changes are required.

Q: Do these parts have the same operating temperature range?

A: Yes. Both parts operate across -40°C to 85°C (TA), making them suitable for identical thermal environments.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ATSAMA5D28C-D1G-CU and ATSAMA5D27C-CUR are ROHS3 compliant and REACH unaffected.

Q: What security features are included in both microprocessors?

A: Both parts include ARM TrustZone, Boot Security, Cryptography acceleration, RTIC, Secure Fusebox, Secure JTAG, Secure Memory, and Secure RTC functionality.

Q: Can I mix these parts in the same production batch?

A: Yes. Since both parts are functionally equivalent with identical specifications, they can be used interchangeably in the same design without affecting system performance or reliability.
