MCB2470 datasheet


The ARM7TDMI based MCB2470 Evaluation Board allows you to generate and test application programs for the NXP (formerly Philips) LPC24xx microcontroller family. With this hands-on process, you can determine the hardware and software requirements for current and future product development.

The Evaluation Board ships with the LPC2478 device that is a superset of several other device variants of the LPC24xx microcontroller series. The Board contains all the hardware components required in a single-chip LPC24xx system.

The Evaluation Board also includes a 320×240 TFT LCD QVGA color display module with a built-in touchscreen.

Reference Datasheet : AN8428GAK, Driver for 3.5inch HDD motor

AN8428GAK is motor comb IC for 3.5inch HDD. By new retract circuit ,reduce external components and shorten the brake time of the disk to improve reliability of HDD. Spindle motor sensor less linear drive.
VCM linear drive , PWM-DAC control. Built-in Retract , 12 V/5 V/3.3 V power monitor, 3.3 V-Regulator.
80-pin TQFP package with exposed heat think.

■ Features
● By new retract circuit ,reduce external components and shorten the brake time 1/2 of the disk to improve reliability of HDD.
● Built-in shock sensor amplifier for mechanical shock protection and 3.3 V regulator for logic semiconductor.
● 10 dB acoustic noise reduction by trapezoidal current on spindle motor drive .
● 80- pin TQFP package with the smallest thermal resistance in the  industry. Meet to increase speed of HDD higher 30 % than previous.
