SOFTWARE FEATURES
Input Data Format
- 1-byte Command code, 3-byte address, 1-byte byte address
512-byte Sequential Read Operation
Built in 9-bit (A0 to A8) pre-settable address counter to support the 512-byte sequential read operation

b. General Description
The MX25L1602 is a CMOS 16,777,216 bit serial Flash EEPROM, which is configured as 2,097,152 x 8
internally. The MX25L1602 features a serial peripheral interface and software protocol allowing operation on a
simple 3- wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output
(SO). SPI access to the device is enabled by CS input.
simple 3- wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output
(SO). SPI access to the device is enabled by CS input.
The MX25L1602 provide sequential read operation on whole chip. The sequential read operation is executed on
a segment (512 byte) basis. User may start to read from any byte of the segment. While the end of the segment is
reached, the device will wrap around to the beginning of the segment and continuously outputs data until CS goes
high.
reached, the device will wrap around to the beginning of the segment and continuously outputs data until CS goes
high.
After program/erase command is issued, auto program/ erase algorithms which program/erase and verify the
specified page locations will be executed. Program command is executed on a page (128 bytes) basis, and erase
command is executed on both chip and sector (8K bytes) basis.

To provide user with ease of interface, a status register is included to indicate the status of the chip. The status
read command can be issued to detect completion and error flag status of a program or erase operation.
When the device is not in operation and CS is high, it is put in standby mode and draws less than 30uA DC
current.
The MX25L1602 utilizes MXIC's proprietary memory cell which reliably stores memory contents even after
100,000 programs and erase cycles.

9. USB INTERFACE
Mstar IC has two input port for USB, therefore air mouse, internal wi-fi interface and USB2 are combined with
HUB. This property is optional. If air mouse and wi-fi interfaces are not aligned, two USB are connected directly to
main IC.

a. General Description
The SMSC USB251xB/xBi hub is a family of low-power, configurable, MTT (multi transaction translator) hub
controller IC products for embedded USB solutions. The x in the part number indicates the number of downstream
ports available, while the B indicates battery charging support. The SMSC hub supports lowspeed, full-speed, and
hi-speed (if operating as a hispeed hub) downstream devices on all of the enabled downstream ports.
