Increased Design Security Through Programmable and Reconfigurable Devices
While a wide variety of techniques exist to enhance design security, many incorporate specialized components and circuitry that
add cost and increase complexity.
Adapticom seeks to enhance security by more highly integrating designs, utilizing the most secure
and advanced programmable and reconfigurable digital, analog, and mixed signal devices.
Recent advances in device integration have allowed the propagation of reconfigurable
devices that encompass a wide variety of common board level functions. The use of such devices has had a
significant positive effect on Design For Security (DFS)
efforts. Rather than adding components and complexity to the design, these components reduce design overhead in a surprising number of ways:
- Reduced component count for simplified BOM.
- Reduced PCB space requirements.
- Increased design revision capability.
- Use of the same devices across multiple products or designs increases purchasing power and simplifies inventory requirements.
- Enhanced design re-use capabilities.
- Simplified R&D through programmable elements.
- Use of similar tools across devices and products reduces engineer educational efforts.
Today's reconfigurable devices have progressed well beyond the FPGA and PAL technologies that proliferated during the 1990's and now include mixed
signal devices such as the Motorola
56800E core-based family
of Hybrid Controllers, which combine the processing power of a DSP and the functionality
of a microcontoller inside a compact 64-pin LQFP. This device features 60 MIPS perforamnce (at 60 MHz), along with 48 KB of on-chip Flash memory
and a comprehensive set of peripehrals. It extends the capabilities of the
Cypress PSoC CY8C27x
contain over 100 reconfigurable analog and digital library components created from 12 fundamental analog and 8 digital blocks. PSoC CY8C27x
Each of these PSoC (Programmable System on Chip) devices contain a 24 MHz 8-bit microcontroller unit (MCU);
16 kbytes of flash memory; 256 bytes of SRAM; an 8x8 multiplier with 32-bit accumulator; power and sleep monitoring circuits;
and a precision real-time clock. The largest device in the family, the
the following resources:
and can be configured to provide such features as:
- I2C 400KHz Interface
- Internal 24 MHz Main Oscillator
- Three Internal Clock Dividers
- Embedded M8C Microprocessor Core
- 16 KBytes Flash Program Memory (with EEProm emulation)
- 256 Bytes of SRAM
- Memory Protection Features
- 8 Multiplexed Analog Inputs
- 4 Analog Outputs w/ 45 mA drive capability
- 4 direct analog input lines
Since the devices have a defined set of analog and digital resources,
that can be configured in many ways
the overall device function is determined entirely by its programmable configuration.
As a result, there are little or no "clues to function" provided by a visual
examination of the PCB.
Many devices, including both the Motorola and Cypress parts
have security features to prevent configuration readback. The reconfigurability
of the devices allow for a tampering defense through "configuration scrubbing", or the
loading of "white" configurations.

"Butterfly" Development Kit)
The MSP430 family consists of several devices featuring different sets of peripherals targeted for various applications.
The devices employ five low power modes and feature a 16-bit RISC CPU, 16-bit registers, digitally controlled oscillator (DCO),
allowing wake-up from low-power modes to active mode in < 6Ás.
The MSP430xW42x series are microcontroller configurations with two built-in 16-bit timers, a comparator, 96 LCD segment drive capability,
a scan interface, and 48 I/O pins.
