Atmel Rolls Out GMR Pre-Amplifier Products for Mobile Hard Disk Drive

3/10/2004 - Atmel® Corporation (Nasdaq: ATML) announced the availability of a new high performance, low voltage GMR pre-amplifier product family designed by the Network Storage Products Business Unit. Total shipment for disk drives in 2003 was over 260 million units. Recent industry data indicates that the total available market for mobile storage products in quarter ending in December 2003 was 16.3 million units. "The number of units being shipped will increase due to new innovative applications for mobile disk drives. Mobility and product differentiation will allow disk drive companies to tap into new markets like video, gaming, camera, and music. These applications require more storage capacity due to the content richness of the applications" said Max Bathaee, Sr. Marketing manager for Atmel Network Storage Unit. "We are focusing on designing devices with highest performance, lowest power dissipation and fastest data rate that are ideal for mobile applications and small form factors of 0.85", 1.0" and 1.8" hard disk drives," he added.

The 3.3V and 5V high performance series read/write Giant Magnetoresistive (GMR) pre-amp, supports up to 500 Mb/s data rate, ideal for 0.85", 1.0" and 1.8" hard disk drives. The devices are available in a one-channel AT78C6001 and two-channel AT78C6002 both with similar capabilities and functions. Both devices support the GMR pre-amp, designed for use with 4-terminal magneto-resistive recording heads.

AT78C6001 and AT78C6002 provide low noise to the GMR head amplifier which is ideal for mobile hard disk drive companies manufacturing 0.85", 1.0" and 1.8" form factors. Additionally, the devices have integrated capacitors, which minimize the designer's need for external components. Both GMR pre-amps are programmable through serial port interfaces. Therefore, Atmel's high performance GMR pre-amplifiers provide lowest signal-to-noise ratio for clarity and channel.

AT78C6001 and AT78C6002 provide GMR ESD protection structure within the reader, which protects the reader heads from static charge without performance degradation. These devices provide GMR read bias current control, write driver, with programmable write current and pre-emphasis programmable thermal asperity detection and correction. AT78C6001 and AT78C6002 are fully characterized and production ready.

AT78C6001 and AT78C6002 are available immediately for customer evaluation. Atmel will provide samples, evaluation board and firmware in addition to technical support. Both devices are available in a 24-pin TSSOP package and it can also be available in variety of other packages based on customer's requirement. The pricing is based on volume and shipment forecast.
