The document describes the features and characteristics of the DS9105 series iButton products, including DS1982-based iButtons, 128 bytes of user-programmable EPROM, available as a set of 12 or individual buttons.

Maxim DS5002FP Secure Microprocessor

The product is a RF transceiver IC for 802.11a/b/g wireless radios.

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accu- rate timekeeping when main power to the device is inter- rupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The DS3231 is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package. The RTC maintains seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. Two programmable time-of- day alarms and a programmable square-wave output are provided. Address and data are transferred serially through an I2C bidirectional bus. A precision temperature-compensated voltage refer- ence and comparator circuit monitors the status of VCC to detect power failures, to provide a reset output, and to automatically switch to the backup supply when nec- essary. Additionally, the RST pin is monitored as a pushbutton input for generating a µP reset. Applications Servers Utility Power Meters Telematics GPS

Package Information

The MAX7328/MAX7329 are 2-wire serial-interfaced peripherals with eight I/O ports. Any port can be used as a logic input or an open-drain output. All input ports are continuously monitored for state changes (transition detection).

The MAX7311 2-wire-interfaced expander provides 16-bit parallel input/output (I/O) port expansion for SMBus™ and I2C™ applications. The MAX7311 consists of input port registers, output port registers, polarity inversion registers, configuration registers, a bus timeout register, and an I2C-compatible serial interface logic compatible with SMBus. The system master can invert the MAX7311 input data by writing to the active-high polarity inversion register. The system master can enable or disable bus timeout by writing to the bus timeout register. Any of the 16 I/O ports can be configured as an input or output. A power-on reset (POR) initializes the 16 I/Os as inputs. Three address select pins configure one of 64 slave ID addresses. The MAX7311 supports hot insertion. All port pins, the INT output, SDA, SCL and the slave address inputs AD0–2 remain high impedance in power down (V+ = 0V) with up to 6V asserted upon them. The MAX7311 is available in 24-pin SO, SSOP, TSSOP, and thin QFN packages and is specified over the -40°C to +125°C automotive temperature range.

DS2502 is a 1024-bit EPROM with a unique 64-bit registration number, an integrated multidrop controller, and supports multiple data access methods. Each memory page can be permanently write-protected.

The document describes the features and characteristics of the DS1721 2-Wire Digital Thermometer and Thermostat, including temperature measurement range, resolution, conversion time, etc.

The DS1232 MicroMonitor™ Chip monitors three vital conditions for a microprocessor: power supply, software execution, and external override.

The MAX7312 is a 2-wire-interfaced expander that provides 16-bit parallel input/output (I/O) port expansion in SMBus™ and I2C applications. The MAX7312 consists of input port registers, output port registers, polarity inversion registers, configuration registers, a bus timeout register, and an I2C-compatible serial interface logic, compatible with SMBus. The system master can invert the MAX7312 input data by writing to the active-high polarity inversion register. The system master can enable or disable bus timeout by writing to the bus timeout register. Any of the 16 I/O ports can be configured as an input or an output. A power-on reset (POR) initializes the 16 I/Os as inputs. Three address select pins configure the part to one of 64 slave ID addresses. The MAX7312 supports hot insertion. All port pins, the INT output, SDA, SCL, and the slave address inputs AD0-2 remain high impedance in power-down (Vt = 0V) up to 6V. The MAX7312 is available in 24-pin SO, SSOP, TSSOP, and thin QFN packages and is specified over the -40°C to +125°C automotive temperature range. For applications requiring I/Os with integrated 100kΩ pullup resistors, refer to the MAX7311 data sheet. Applications include Servers/Blades, RAID Systems, Medical Equipment, Instrumentation and Test Measurement, Networking.
