71321LA55PPGI - Renesas Electronics

Description: The 71321 is a high-speed 2K x 8 Dual-Port Static RAM with internal interrupt logic for interprocessor communications. It is designed to be used as a stand-alone 8-bit Dual-Port RAM or as a "MASTER" Dual-Port RAM together with the 71421 "SLAVE" Dual-Port in 16-bit-or-more word width systems which would result in full-speed, error free operation without the need for additional discrete logic. An automatic power down feature, controlled by CE, permits the on chip circuitry of each port to enter a very low sta

71321LA55PPGI Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the 71321LA55PPGI is -40°C to 125°C.
  • The POR circuitry in the 71321LA55PPGI is designed to reset the device during power-up. To handle POR, ensure that the power supply voltage (VCC) rises slowly and monotonically to avoid false resets. A minimum rise time of 1 ms is recommended.
  • The maximum clock frequency supported by the 71321LA55PPGI is 55 MHz.
  • To configure the 71321LA55PPGI for low-power operation, use the power-down mode (PDN) pin to reduce power consumption. Additionally, use the clock gating feature to disable clocks to unused modules and peripherals.
  • The maximum current rating for the I/O pins of the 71321LA55PPGI is 4 mA per pin.
