H5TC4G63AFR-PBR - 4Gb DDR3L SDRAM 256Mx16 | SK Hynix
The H5TC4G63AFR-PBR is a 4Gb DDR3L SDRAM (Double Data Rate 3 Low Voltage) organized as 256M x 16, manufactured by SK Hynix. It operates at a supply voltage of 1.35V (with 1.5V compatibility) and is housed in a 96-ball FBGA package (PBGA96). This memory device is designed for high-speed data transfer with a data rate of 1600 Mbps (PC3L-12800), featuring a CAS latency of 11 and a tRCD/tRP of 11. The device supports on-die termination (ODT), programmable CAS latency, and burst lengths of 8 and 4 (with burst chop). It is compliant with the JEDEC DDR3L standard, ensuring interoperability with a wide range of controllers.
DDR3L SDRAM is a type of synchronous dynamic random-access memory that transfers data on both edges of the clock signal, effectively doubling the data rate. It is a low-voltage variant of DDR3, operating at 1.35V instead of 1.5V, which reduces power consumption by approximately 15-20% compared to standard DDR3. DDR3L is part of the DDR SDRAM family, which includes DDR, DDR2, DDR3, and DDR4, and is widely used in computing, networking, and embedded systems. The low-voltage operation makes it ideal for power-sensitive applications such as laptops, servers, and industrial electronics.
Key features of the H5TC4G63AFR-PBR include a 16-bit I/O interface, 8 internal banks, and a burst length of 8 (BL8) with burst chop (BC4). It supports auto refresh and self refresh modes, with a refresh interval of 7.8us at 85C and 3.9us at 95C. The device has a programmable output driver impedance and on-die termination for improved signal integrity. It also features a temperature-compensated self-refresh (TCSR) and a partial array self-refresh (PASR) for power savings. The package is a 96-ball FBGA with a 0.8mm ball pitch, measuring 13.5mm x 9.0mm, and is RoHS compliant.
Technically, the H5TC4G63AFR-PBR uses a CMOS process and supports a clock frequency up to 800 MHz (DDR3L-1600). It has a tCK of 1.25ns and a tRCD of 13.125ns. The device includes a mode register set (MRS) for configuration and supports write leveling and read leveling for improved signal integrity. The I/O interface is SSTL-15 compatible, and the device supports a data strobe (DQS) differential pair. The memory is organized into 8 banks of 32M x 16, providing a total capacity of 4Gb. The device is designed for high-reliability applications and is available in a lead-free, halogen-free package.
Typical applications for the H5TC4G63AFR-PBR include embedded systems, networking equipment (routers, switches), industrial PCs, and consumer electronics such as set-top boxes and smart TVs. Its low-voltage operation and high density make it suitable for memory-intensive applications where power efficiency is critical. The device is also used in automotive infotainment systems and medical devices that require reliable, high-speed memory.
When designing with this device, ensure proper decoupling capacitors (0.1uF and 1uF) are placed near the VDD and VDDQ pins to minimize noise. The VREFCA and VREFDQ should be bypassed with 0.1uF capacitors. The device requires a stable 1.35V supply and a separate 1.35V VDDQ supply. For optimal signal integrity, route the DQ, DQS, and address lines with matched trace lengths and controlled impedance (typically 50 ohms single-ended, 100 ohms differential).
