In embedded systems and communication devices,the choice of memory chips directly impacts the power consumption and stability of the entire system.As an authorized agent of JSC,Yingshang Microelectronics has been directly supplying JSC's original SDR SDRAM memory chips for a long time.Among them,the EM856164PAY-75UE model,with its low power consumption and high compatibility,has become the preferred solution for many engineers.
I.What is SDR SDRAM?
Many developers tend to confuse"SDR"with"DDR".In fact,SDR stands for Single Data Rate,while DDR represents Double Data Rate.Both share the same underlying technology-SDRAM,which stands for Synchronous Dynamic Random Access Memory.
II.Core working characteristics of SDR SDRAM:
In each clock cycle,SDR SDRAM can only complete one data transmission(read or write).Data operations occur at the rising edge or falling edge of the clock signal(single-edge triggering),so the theoretical bandwidth is clock frequency×bit width.For example,at 133MHz and 16-bit width,the theoretical peak bandwidth is approximately 266MB/s.In contrast,DDR SDRAM transmits data once at each of the rising and falling edges of a clock cycle,doubling the bandwidth,but also increasing power consumption and timing complexity accordingly.
III.Why choose JSC SDR SDRAM memory chip EM856164PAY-75UE?
①Low power consumption advantage:With a 1.8V operating voltage and JSC low-power process,it achieves over 40%energy savings compared to traditional 2.5V or 3.3V SDR SDRAM at the same frequency,making it particularly suitable for applications sensitive to battery life,such as portable devices,IoT modules,and smart meters.
②Mature and stable SDR interface:For MCUs or SoCs(such as certain ARM9,Cortex-M7 core chips)that still use SDR SDRAM controllers,the EM856164PAY-75UE can directly replace or upgrade existing designs without requiring additional level conversion or complex timing adjustments.
③Wide temperature operation guarantee:The range of-30°C to 85°C covers most outdoor and industrial on-site environments,avoiding data errors caused by temperature fluctuations.
④Original factory direct supply quality:As an authorized agent,Yingshangwei guarantees that all EM856164PAY-75UE products are from the original factory of JSC and are brand new batches.We provide complete technical specifications and after-sales support.
IV.The product specifications for the JSC SDR SDRAM memory chip EM856164PAY-75UE are as follows:
①Storage capacity:256Mbit,data bit width 16bit(x16)
②Number of internal banks:4 banks,supporting cross-operation to enhance efficiency
③Operating voltage:1.8V,significantly lower than traditional 3.3V SDRAM,suitable for battery-powered devices
④Packaging form:54-ball FPBGA,compact packaging for easy PCB layout
⑤Maximum frequency:133MHz,meeting the requirements of mainstream embedded processors
⑥Operating temperature range:-30°C~85°C,covering both industrial and consumer-grade scenarios
