Infineon Technologies CY7C1061DV18-15ZSXIT

Overview

CY7C1061DV18-15ZSXIT from Cypress Semiconductor is a 16-Mbit (1 M × 16) asynchronous CMOS Static RAM with 15 ns access time, 1.7–2.2 V core supply, and dual chip enable (CE1/CE2) for flexible memory expansion in embedded controllers and FPGA co-processors. It supports byte-wide writes via BHE/ BLE, delivers 150 mA active current at 67 MHz, and retains data down to 1.5 V.

For engineers reviewing the CY7C1061DV18-15ZSXIT datasheet, CY7C1061DV18-15ZSXIT pinout, CY7C1061DV18-15ZSXIT application, or CY7C1061DV18-15ZSXIT equivalent, key selection criteria include TSOP II pinout compatibility, 15 ns tAA timing under 1.8 V operation, low-power standby modes (ISB2 = 25 mA), and TTL-compatible I/O signaling in industrial temperature range.

Technical Context

The CY7C1061DV18-15ZSXIT implements a fully static 1,048,576 × 16-bit memory array with independent high- and low-byte enables (BHE/BLE), enabling partial-word writes without read-modify-write cycles. Its dual CE architecture (CE1 LOW + CE2 HIGH for selection) allows hierarchical memory mapping in multi-bank systems.

It features automatic power-down on chip deselect, 1.5 V data retention capability, and high-impedance I/O control synchronized to OE, WE, BHE, and BLE transitions - ensuring clean bus sharing in shared-memory architectures with microprocessors and DSPs.

FAQ

What is the minimum VCC required for full functionality?

The CY7C1061DV18-15ZSXIT requires VCC ≥ 1.7 V for guaranteed read/write operation across the full industrial temperature range. Below 1.7 V, timing parameters (e.g., tAA = 15 ns) and DC specifications (VOH/VOL) are not assured, though data retention remains valid down to 1.5 V with CE deselected.

Can BHE and BLE be asserted simultaneously for full 16-bit access?

Yes - asserting both BHE and BLE LOW enables full 16-bit parallel access to I/O0–I/O15 during read or write operations. This configuration matches standard 16-bit bus interfaces and eliminates partial-word penalties in burst transfers.

How does the TSOP II "revolutionary" pinout improve signal integrity?

The 54-pin TSOP II package places multiple VCC and VSS pins centrally and symmetrically (e.g., pins 16, 35, 45, 47, 51, 54 for VCC; pins 8, 31, 44, 46, 50, 53 for VSS), minimizing ground bounce and supply noise during high-speed toggling of all 16 I/O lines and address bits.

Is this device compatible with 3.3 V I/O systems?

No - the CY7C1061DV18-15ZSXIT is strictly a 1.7–2.2 V core device with TTL-compatible input thresholds (VIH = 1.4 V, VIL = 0.4 V), but its outputs swing only to ~1.4 V (VOH) under 1.8 V VCC. Direct connection to 3.3 V buses requires level translation to avoid overvoltage damage or logic misreads.
