General Description

The MAXQ1004 is a low-power microcontroller that

integrates a 10-bit ADC, 1-Wire

slave interface, SPIK,

AES encryption, random-number generator (RNG), and

temperature sensor with a 16-bit MAXQ

pipelined CPU.

Performance bandwidth is sufficient to handle master

or slave challenge-response authentication in portable

devices.

The device incorporates 16KB of flash memory and 640B

of RAM. Factory programming of a customer secret key

is available upon request. The microcontroller runs within

a wide 1.7V to 3.6V operating range.

For the ultimate in low-power performance, an ultra-low-

power stop mode (300nA typ) is available. In this mode,

only a minimum amount of circuitry is powered to sup-

port detection of the start of a 1-Wire transaction. When

1-Wire activity is detected, the microcontroller is turned

on and the command is executed in an atomic fashion.

This allows for stateless operation between commands,

providing the highest reliability and lowest power con-

sumption.

MAXQ1004 1-Wire and SPI Authentication Microcontroller Detailed Description The MAXQ1004 is a low-power, high-performance, 16-bit MAXQ microcontroller providing the high security and reliability demanded in today’s portable electronics, battery chargers, and battery packs. An ISO/IEC 9797-1 standards-based authentication protocol is available as standard application code. A 1-Wire communication interface minimizes batterypack connections required to authenticate and monitor battery health.

1-Wire and SPI Authentication Microcontroller An internal bootstrap loader allows the device to be reloaded over a simple JTAG interface. As a result, software can be upgraded in-system, eliminating the need for a costly hardware retrofit when updates are required. Remote software uploads are possible that enable physically inaccessible applications to be frequently updated. If in-system programmability is not required, a commercial gang programmer can be used for mass programming.

MAXQ1004 1-Wire and SPI Authentication Microcontroller Slave Functionality The 1-Wire slave provides three functions. The first is that of a totally independent slave function, which can be externally accessed at any time to verify its identity. The 1-Wire front-end functions in an identical fashion to that of the DS1990 serial ID to verify the serial ID number. The bus master must provide one of the ROM function commands: a valid 1-Wire command received, or a power-fail reset.

1-Wire and SPI Authentication Microcontroller Embedded debugging capability is available through the JTAG-compatible test access port (TAP). Embedded debug hardware and embedded ROM firmware provide in-circuit debugging capability to the user application, eliminating the need for an expensive in-circuit emulator. See Figure 2.
