Product Details
ATSHA204A-MAHDA-T - Microchip CryptoAuthentication™ Security IC
The ATSHA204A-MAHDA-T is a specialized hardware security solution from Microchip Technology. It integrates a secure EEPROM and a high-speed hardware accelerator for the SHA-256 hash algorithm. Designed to provide cost-effective anti-counterfeiting, secure authentication, and key storage, this IC ensures that only authorized peripherals and firmware can interact with your system.
Security Focus: Features hardware-level protection against invasive physical attacks, ensuring that sensitive keys and secrets remain unreadable by external parties.
Overview & Security Architecture
The ATSHA204A-MAHDA-T belongs to Microchip's CryptoAuthentication™ family, which is widely recognized as one of the most flexible and robust security IC portfolios in the market. It utilizes a Challenge-Response protocol to verify the authenticity of a device without ever exposing the internal secret keys over the communication bus.
This device includes 4.5Kb of secure EEPROM, which can be used for storing keys, read-only data, or consumption tracking (monotonic counters). Its unique 72-bit Serial Number ensures that every chip produced is globally distinct, further enhancing its anti-cloning capabilities.
About Microchip Technology
Microchip Technology Inc. is a leading provider of smart, connected, and secure embedded control solutions. Their products serve thousands of diverse customer applications across the industrial, automotive, consumer, aerospace and defense, communications, and computing markets.
Microchip's security division is at the forefront of hardware-based root-of-trust solutions, helping manufacturers defend their intellectual property (IP) and brand reputation through easy-to-implement cryptographic hardware.
Key Advantages
Executes high-speed cryptographic operations significantly faster than software-based implementations on a standard MCU.
Prevents aftermarket third-party peripherals from working with your products through secure handshake protocols.
Standby current is less than 150nA, making it ideal for the most power-sensitive wearable and IoT devices.
Supports both standard I2C and Single-Wire interfaces, allowing for minimal pin usage in space-constrained designs.
Package & Mechanical Specs
The ATSHA204A-MAHDA-T is housed in an ultra-compact 8-pad UDFN package, optimized for high-density mobile and embedded board layouts.
- Package Type: UDFN-8-EP
- Dimensions: 2.0 mm x 3.0 mm
- Mounting: Surface Mount (SMT)
- Operating Temp: -40°C to +85°C (Industrial Grade)
Pin Functions
The ATSHA204A is designed for simplicity, requiring very few connections to the host microcontroller.

Equivalent & Replacement Guide
When seeking a replacement for the ATSHA204A-MAHDA-T, functional compatibility depends heavily on the firmware's implementation of the cryptographic handshake.
- ATECC608B: A higher-tier upgrade featuring ECC (Elliptic Curve Cryptography) in addition to SHA-256 for stronger IoT security.
- ATSHA204A-SSHDA-T: The same IC functionality but in an 8-lead SOIC package.
- MOD208-DMCF-R (MODSEMI): A functional equivalent from MODSEMI with the same UDFN-8-EP (2x3) package for applications looking for a cost-optimized cross-manufacturer alternative.
Typical Application Fields
Anti-Counterfeiting
Authenticating printer cartridges, e-cigarette pods, and medical consumables to ensure brand safety.
IoT Device Security
Providing a hardware-based root of trust for smart home devices and industrial sensors.
Secure Boot Support
Assisting a host MCU in verifying the integrity and origin of the firmware before execution.
Accessory Validation
Ensuring that only certified third-party cables, batteries, and peripherals can charge or sync with host devices.
Quality & Authenticity
- FIPS Compliance: Designed to meet high-level security certification standards.
- Anti-Tamper: Active shield and internal voltage monitoring prevent physical extraction of secrets.
- Factory Provisioning: Microchip offers secure factory pre-provisioning services to preload keys during the wafer stage.
