Microchip Technology AT88CK301ADP

Overview

AT88CK301ADP from Microchip Technology (formerly Atmel) is an adapter kit designed to reconfigure the 10-pin interface header of the AT88CK109BK8 CryptoAuthentication daughterboard for compatibility with non-standard MCU or baseboard pinouts. It includes a 10-pin squid cable with color-coded wires (black to brown), supports I²C and SWI protocols, and enables secure authentication development using ATSHA204 devices in embedded security prototyping.

For engineers reviewing the AT88CK301ADP datasheet, AT88CK301ADP pinout, AT88CK301ADP application, or AT88CK301ADP equivalent, this adapter kit addresses physical layer interoperability between the AT88CK109BK8 daughterboard and host platforms with mismatched 10-pin header assignments - critical when integrating CryptoAuthentication into custom AVR, ARM, or FPGA-based evaluation systems.

Technical Context

The AT88CK301ADP is a passive wiring adapter that remaps signal routing between the fixed 10-pin header on the AT88CK109BK8 daughterboard and alternate target boards. It does not contain active components, ICs, or firmware, and introduces no timing delay, voltage translation, or protocol conversion.

Its design directly corresponds to the pin definitions in Table 2-1 (VCC, GND, SDA, SCL, and six NC pins) and uses a standardized 10-conductor flat cable with color coding per Table 2-2. No power regulation, level shifting, or ESD protection is integrated.

Manufacturer

Microchip Technology acquired Atmel in 2016 and maintains legacy crypto development tools under the CryptoAuthentication™ brand. The company specializes in secure microcontrollers, hardware security ICs, and associated evaluation infrastructure.

The AT88CK301ADP belongs to the CryptoAuthentication Starter Kit ecosystem and was developed to extend hardware flexibility for engineers implementing secure authentication with ATSHA204-based designs - specifically addressing mechanical interface mismatches in rapid-prototyping workflows.

FAQ

What is the primary function of the AT88CK301ADP adapter kit?

The AT88CK301ADP adapter kit is a passive 10-pin squid cable assembly that remaps the fixed pinout of the AT88CK109BK8 daughterboard to match alternative MCU or baseboard headers. It enables physical connectivity without modifying the daughterboard or host platform, preserving I²C and SWI signal integrity for ATSHA204-based security development. AT88CK301ADP contains no active components or logic.

Does the AT88CK301ADP include any integrated circuitry or firmware?

No, the AT88CK301ADP is a purely passive interconnect solution consisting only of a color-coded 10-conductor flat cable and crimped connectors. It contains no ICs, microcontrollers, memory, or programmable elements. All functionality is limited to conductor-level signal routing as defined in Table 2-2 of the AT88CK109BK8 Hardware User Guide. AT88CK301ADP performs no voltage translation, level shifting, or protocol handling.

Which daughterboard is the AT88CK301ADP designed to interface with?

The AT88CK301ADP is explicitly designed for use with the AT88CK109BK8 CryptoAuthentication daughterboard. It mates directly with that board's 10-pin header and provides a flexible wiring path to external hosts. It is not compatible with other Atmel/Microchip daughterboards such as AT88CK101BK8 or AT88CK590 series without mechanical or electrical adaptation. AT88CK301ADP's pin definitions are locked to the AT88CK109BK8 specification.

Can the AT88CK301ADP be used to connect the AT88CK109BK8 to an Arduino or Raspberry Pi?

Yes - but only if a custom adapter or breakout board bridges the 10-pin header to the target platform's native pin layout. The AT88CK301ADP itself provides no pin reordering beyond its fixed color-coded mapping; users must manually assign SCL, SDA, VCC, and GND from the cable to correct GPIO or I²C pins on Arduino or Raspberry Pi. AT88CK301ADP does not include level-shifting or pull-up resistors required for 3.3V/5V interoperability.

Is the AT88CK301ADP RoHS-compliant and lead-free?

Yes, the AT88CK301ADP conforms to RoHS Directive 2011/65/EU and is lead-free. As a legacy Atmel product released in 2011 under document 8742A–CRYPTO–3/11, it was manufactured to Atmel's standard environmental compliance requirements applicable at time of production.
