TUTORIAL 3675

Protecting the R&D investment with Secure Authentication from Maxim

Abstract: In the age of identity theft and faked IDs, achieving positive identification is of paramount importance. This is not only true for individuals, but also applies to electronic products. Manufacturers of nearly all equipment types need to protect their products against the counterfeit components that aftermarket companies will attempt to introduce into the OEM supply chain. Secure authentication provides a strong electronic solution to address this threat as well as additional useful end-product features.

Part 1:

Maxim – DS28E22: DeepCover Secure Authenticator with SHA-256 and 2Kb User EEPROM, to protect IP

DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible.

Key Features
• Symmetric Key-Based Bidirectional Secure Authentication Model Based on SHA-256
• Dedicated Hardware-Accelerated SHA Engine for Generating SHA-256 MACs
• Strong Authentication with a High Bit Count, User-Programmable Secret, and Input Challenge
• 2048 Bits of User EEPROM Partitioned Into 8 Pages of 256 Bits
• User-Programmable and Irreversible EEPROM Protection Modes Including Authentication, Write and Read Protect, and OTP/EPROM Emulation
• Unique, Factory-Programmed 64-Bit Identification Number
• Single-Contact 1-Wire Interface (I2C version is DS28C22)
• Operating Range: 3.3V ±10%, -40°C to +85°C, Low-Power 5μA (typ) Standby

Part 2:

BlueGiga – BLE121LR Bluetooth Smart Long Range Module

BLE121LR is a Bluetooth Smart Long Range module targeted for Bluetooth Smart applications where the best possible RF performance and range are required. At +8 dBm TX power and -98 dBm sensitivity BLE121LR has best-in-class RF performance and can provide Bluetooth Smart connectivity up to 450 meters. BLE121LR integrates all features required for a Bluetooth Smart application: Bluetooth radio, software stack and GATT based profiles. and it can also host end user applications, which means no external micro controller is required in size, price or power constrained devices. BLE121LR Bluetooth Smart module also has flexible hardware interfaces to connect to different peripherals or sensors. Although BLE121LR Bluetooth Smart Long Range Module is target for applications requiring high RF performance, it is still has relatively low power consumption and can be powered using a standard 3V coin cell battery.

Key Benefits
• Best-in-Class Radio Performance
   o +8 dBm TX power and -98 dBm sensitivity
   o up to 450 meter range
• Fully Integrated Bluetooth Smart solution
   o Integrated Bluetooth Radio, micro controller and software stack
   o Fast time to market. Low development risks
• Application Hosting Capabilities
   o All application code can be executed on the BLE121LR
   o No need for external micro controller
   o Lower cost and smaller physical size
• Flash-based
   o Firmware is field upgradeable
   o Application data can be stored on the flash
   o Settings can be stored on the flash
• Bluetooth and Regulatory Qualifications
   o Proven interoperability
   o Minimal qualification costs

Part 3:

Micrel – MIC23099: Single AA/AAA Cell Step-Up/Step-Down Regulators with Battery Monitoring

The MIC23099 is a high-efficiency, low-noise, dual-output, integrated power-management solution for single-cell alkaline or NiMH battery applications.

To minimize switching artifacts in the audio band, both the converters are design to operate with a minimum switching frequency of 80kHz for the buck and 100kHz for the boost. The high current boost has a maximum switching frequency of 1MHz, minimizing the solution footprint.

The MIC23099 incorporates both battery-management functions and fault protection. The low-battery level is indicated by an external LED connected to the LED pin

Key Features
• VIN range from 0.85V to 1.6V
• VOUT1 (step-up) adjustable from 1.8V to 3.3V
• VOUT2 (step-down) adjustable from 1.0V to VOUT2
• VOUT1/400mW and VOUT2/30mA from a single cell
• Minimizes switching noise in the audio band
• Step-up regulator with output disconnect in shutdown
• VOUT1, above 90% efficiency for 5mA to 200mA
• Anti-ringing control circuit to minimize EMI
• Turn-on inrush current limiting and soft-start
• Automatic output discharge
• Low-battery indicator
• Power Good (PG) output
• Low output ripple < 10mV
• Short-circuit and thermal protection
• 14-pin 2.5mm × 2.5mm × 0.55mm thin QFN (TQFN) package

Part 4:

APS – Compact easy loading 5V thermal printer from Advanced Printing Systems

The ELM205-HS from APS' ELM 200 Series

Features
• Compact design - low weight
• No loose wiring - a single flex-cable houses all wiring
• Ergonomic design - centered paper path allows uniform and aesthetic housing design
• Patented easy loading design
• Print speed of to 95 mm/s for HS and 75 mm/s for LV version
