HM530281RTT-20

The HM530281RTT-20 is in the HM530281R series family. they are memory products provide completely asynchronous I/O and operate at the high speed of 50 MHz.  The HM530281R series memory products provide reset, jump, and line increment/hold pointer control functions that can be used in synchronization with independent clocks on each of the I/O ports.Memory can be accessed immediately without any waiting period after the execution of these functions.

Features of the HM530281RTT-20 are:(1)Organization:  331,776-word * 8-bit; (2)Completely asynchronous operation of the serial read port and write port.-- Internal generation of read and write addresses; (3)--Internal memory operation control provided on-chip; (4)High speed read/write cycle time:  50 MHz; (5)Reset, jump functions:Independent execution for read and write ports, Can be executed with arbitrary timing,Allow immediate access after execution (read/write) (for the jump function, when the address setup iscomplete),Jump address specifiable in 32-word units; (6)2 dimensional address; (7) Line increment/hold address pointer control function; (8) Window scan function; (9) Can handle HDTV, NTSC, and PAL standards: Line length:  Up to 1152 bits (Arbitrary line lengths can also be handled by using the line reset function.)Line count:   Up to 324 lines; (10)Built-in self-refresh eliminates the need for external refresh control.; (11)Power supply voltage:  V  = 5.0 V ± 10%.

The absolute maximum ratings of HM530281RTT-20 the can be summarized as:(1)Pin voltage: 1.0 to +7.0 V; (2)Power dissipation : 1.0 W; (3)Operating temperature : 0 to +70 °C; (4)Storage temperature : 55 to +125 °C; (5)Storage temperature (when biased): 10 to +85 °C.If you want to know more information such as the electrical characteristics about the HM530281RTT-20, please download the datasheet in www.seekic.com or www.chinaicmart.com.
