7035L15PFG - Renesas Electronics

Description: The 7035 is a high-speed 8K x 18 Dual-Port Static RAM designed to be used as a stand-alone 144K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 36-bit or more word systems. This MASTER/SLAVE approach in 36-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. An automatic power down feature controlled by Chip Enable (CE) permits the on-chip circuitry of each port to enter a very low standby power mode.

7035L15PFG Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VCC first, followed by VDD, and then the input clock signal. This ensures proper initialization and prevents potential latch-up conditions.
  • The 7035L15PFG uses a 4-pin JTAG interface. Connect the TCK pin to the clock signal, TDI pin to the data input, TDO pin to the data output, and TMS pin to the mode select signal. Ensure proper signal termination and follow the IEEE 1149.1 standard for JTAG communication.
  • The maximum allowed clock skew between the input clock and the output clock is 1 ns. Exceeding this limit may result in incorrect data transfer or system malfunction.
  • To implement a CDC in the 7035L15PFG, use a synchronizer circuit or a FIFO buffer to transfer data between clock domains. Ensure proper metastability resolution and data integrity by following established CDC design practices.
  • Follow a multi-layer PCB design with a solid ground plane and a separate power plane. Ensure good thermal conductivity by using thermal vias and a heat sink if necessary. Keep sensitive analog signals away from high-current digital signals and follow the recommended pinout and layout guidelines in the datasheet.
