The reversible software write-protect on four individual blocks, faster data rates and SMBus
compatibility offers DRAM manufacturers added flexibility to enable new features in the high-speed PC, laptop and graphic card markets.
Interface -- Atmel's embedded TPM is the only TPM on the market to offer a system management bus (SMBus
Its dual SMBus
feature, small form factor and support for a wide range of operating voltages make the SST89C58RC MCU an ideal solution for numerous applications, including HDMI, HDTVs, A/V receivers, home appliances, industrial instruments, notebook PCs, DVD players, Blu-ray players, RF modules and security applications such as fingerprint identification.
The I2C-based SMBus
(System Management Bus) has been used for several years to manage batteries, chargers, and backlight systems, and has been considered an ideal basis for the PMBus.
For enhanced system performance monitoring, the specific cause of a fault in any of a slot's five supplies is recorded in internal registers and is accessible via the SMBus
interface, offering the system design engineer comprehensive system diagnostic capabilities.
Two-wire digital interface compatible with SMBus
The TSL2550 Ambient Light Sensor is the industry's first ambient light sensor that converts light intensity to a digital output capable of direct SMBus
3VAUX gate driver circuits, current sense, and power MOSFETs -- Programmable inrush current limiting with active current regulation to control inrush current -- Dual-level, dual-speed overcurrent detection for quick fault response without nuisance tripping -- Allows for smaller MOSFETs and less PCB space for lower system cost -- Comes in a 48-pin TQFP package -- A high-accuracy, user-adjustable overcurrent detection timer eliminates false or "nuisance" tripping of the primary electronic circuit-breaker -- Slot power control with "Power-is-Good" and fault status reporting: -- Via software over the SMBus
interface or -- Via dedicated hardware input/output lines -- Hot-Plug Interface, or HPI -- Voltage-tolerant I/O for compatibility with SMBus
The devices then communicate with each other via the SMBus
and can operate independent of a host controller.
Summary of Features: MIC281 Low-Cost IttyBitty(TM) Thermal Sensor -- Measures Remote Temperature With 8-Bit Resolution -- +/-3degC Accuracy From +60degC To +100degC -- Superior Noise Immunity For High System Accuracy -- 2-Wire I2C/SMBus
Compatible Serial Interface With Voltage-Tolerant I/O -- SMBus
Timeout To Prevent Bus Lock-Up -- Failsafe Response To Diode Faults -- Low Power Shutdown Mode -- 3.
Included in the POL reference design is a pre-configured software kernel that features active dynamic dead time control for maximum operating efficiency, non-linear control response for fast transient response, and SMBus
port capable of supporting industry-standard communication protocols.
Software ease-of-use features include the SMBus
Alert Response Address protocol, programmable resolution, mask and status bits for all interrupt sources, S/W reset, and ID registers.
