Bi-directional data path for flexible buffering

Programmable flags to indicate programmable thresholds

Retransmit capability to re-read stored data

Depth and width expansion options for larger systems

3.0–3.6 V operation, CMOS logic levels

66.7 MHz data rate, 9.5 ns access time

Commercial temperature range 0°C to 70°C

Standard 120-HLQFP package for SMT assembly

Key Advantages

High throughput at 3.3 V for modern digital systems

Simplifies interfacing between different clock domains with synchronous control

Programmable flags streamline flow control and status monitoring

Retransmit adds flexibility for error recovery and repeat reads

Expansion in width/depth scales easily to wider buses or deeper buffers

Familiar LQFP footprint helps reduce PCB and manufacturing complexity

Packaging

Type: 120-HLQFP (LQFP style, high-leaded variant)

Material: Molded plastic, leaded gull-wing terminations

Size: 14 x 14 mm body outline

Pin configuration: 120 pins arranged on four sides; includes 36-bit data I/O and control pins (clocks, enables, flags)

Mounting: Surface-mount (SMT)

Supplier device package: 120-HLQFP (14 x 14)

Delivery form: Tray

Thermal characteristics: Board-dependent; designed for commercial 0°C to 70°C operation. For θJA, power dissipation, and exact thermal limits, refer to the datasheet.

Electrical properties: 3.0–3.6 V supply, synchronous control, bi-directional bus, up to 66.7 MHz. Access time 9.5 ns. Note: The provided “Current Supply (Max): 350A” value appears atypically high; please verify the correct current rating in the datasheet.

Lifecycle

Status: This is a mature, RoHS non-compliant device; availability may be limited in some regions. Not indicated as newly discontinued in the provided data, but plan for lifecycle risk and consider second sources.

Equivalent or alternative models (verify pinout, timing, flags, and electrical compatibility):

- Renesas/IDT 72V36100 family (1K x 36 synchronous FIFO, 3.3 V, comparable speed grades)

- Renesas/IDT 72V36110 and 72V36120 families (1K x 36 variants, 3.3 V)

- Cypress/Infineon CY7C42xxV/CY7C43xxV families (1K x 36 synchronous FIFOs at 3.3 V; specific models depend on required speed, flags, and package)

- Texas Instruments SN74V36xx series (TI synchronous FIFO family; select 1K x 36 options where available)
