/Winbond W9412G6KH-5 16 BITS DDR SDRAM

Winbond W9412G6KH-5 16 BITS DDR SDRAM

The -5/-5I grades are compliant to the DDR400/CL3 specification (the -5I industrial grade which is
guaranteed to support -40°C ≤ TA ≤ 85°C).

  • Brand:

    Winbond
  • Product Details
GENERAL DESCRIPTION

W9412G6KH is a CMOS Double Data Rate synchronous dynamic random access memory (DDR
SDRAM); organized as 2M words  4 banks  16 bits. W9412G6KH delivers a data bandwidth of up
to 400M words per second. To fully comply with the personal computer industrial standard,
W9412G6KH is sorted into the following speed grades: -5, -5I and -6I.

The -5/-5I grades are compliant to the DDR400/CL3 specification (the -5I industrial grade which is
guaranteed to support -40°C ≤ TA ≤ 85°C).

The -6I industrial grade is compliant to the DDR333/CL3 specification which is guaranteed to support
-40°C ≤ TA ≤ 85°C.

All Inputs reference to the positive edge of CLK (except for DQ, DM and CKE). The timing reference
point for the differential clock is when the CLK and CLK signals cross during a transition. Write and

Read data are synchronized with the both edges of DQS (Data Strobe).


By having a programmable Mode Register, the system can change burst length, latency cycle,

interleave or sequential burst to maximize its performance. W9412G6KH is ideal for any high

performance applications.

DUAL/QUAD SPI For Industrial & Industrial Plus Grade The W25Q256JV supports standard SPI, Dual SPI and Quad SPI operation. Standard SPI instructions use the unidirectional DI (input) pin to serially write instructions, addresses or data to the device on the rising edge of the Serial Clock (CLK) input pin. Standard SPI also uses the unidirectional DO (output) to read data or status from the device on the falling edge of CLK.
