Product details
Overview
CY7C1362C-166AJXC from Infineon Technologies (formerly Cypress) is a 9-Mbit synchronous pipelined SRAM with 512K × 18 organization, 166 MHz maximum clock frequency, 3.5 ns clock-to-output time, 3.3 V core supply (VDD), and 2.5 V/3.3 V I/O support (VDDQ), deployed in high-speed networking line cards for packet buffering.
For engineers reviewing the CY7C1362C-166AJXC datasheet, CY7C1362C-166AJXC pinout, CY7C1362C-166AJXC application, or CY7C1362C-166AJXC equivalent, key selection criteria include burst mode compatibility (Intel Pentium® interleaved/linear), synchronous self-timed write capability, IEEE 1149.1 JTAG boundary scan support, and TQFP-100 Pb-free packaging with dual chip enable (CE1/CE2).
Technical Context
The CY7C1362C implements a synchronous, clocked architecture where all address, data, and control inputs (ADSP, ADSC, ADV, BWA–BWD, GW, BWE) are registered on the rising edge of CLK. Its internal two-bit burst counter generates sequential addresses during burst reads/writes under ADV control.
It supports byte-selectable writes (1-, 2-, or 4-byte width) via dedicated byte write enables and features asynchronous OE and ZZ (sleep) pins. The device operates with separate VDD (3.3 V) and VDDQ (2.5 V or 3.3 V) supplies, ensuring JEDEC JESD8-5 compliance for mixed-voltage system interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 9 Mbit (512K × 18), enabling compact 18-bit wide data path buffering without external width expansion. |
| Max Clock Frequency | 166 MHz - defines maximum sustained burst throughput of 166 million transfers per second. |
| Access Time | 3.5 ns clock-to-output - guarantees deterministic read latency for real-time packet forwarding logic. |
| Core Supply Voltage | 3.3 V ± 0.3 V (VDD) - compatible with legacy 3.3 V system rails and eliminates need for core voltage regulators. |
| I/O Supply Voltage | 2.5 V or 3.3 V (VDDQ) - allows direct interface to both 2.5 V ASICs and 3.3 V FPGAs without level shifters. |
| Burst Mode | User-selectable Intel Pentium® interleaved or linear sequence - matches standard CPU bus protocols for seamless co-processor integration. |
| Power Dissipation | 180 mA max operating current - enables thermal management in dense multi-SRAM memory subsystems. |
Pinout & Package
Package: 100-pin Pb-free Thin Quad Flat Package (TQFP), 14 mm × 20 mm × 1.4 mm body, 0.5 mm pitch, JEDEC MO-145AC compliant. Pinout corresponds to "AJ Version" (2-chip-enable configuration) as indicated by suffix 'J' in CY7C1362C-166AJXC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Positive-edge-triggered system clock input | Synchronizes all registered inputs/outputs; determines maximum operational frequency (166 MHz). |
| ADSP / ADSC | Address strobe processor / controller | Triggers registration of address and control signals; selects between processor- or controller-initiated access timing. |
| ADV | Address valid advance signal | Controls internal burst counter to generate next address in sequence; enables pipelined burst operation. |
| CE1 / CE2 | Chip enable inputs (active low) | Enable device operation; dual CE supports depth expansion or bank selection in multi-SRAM systems. |
| OE | Asynchronous output enable (active low) | Allows output drivers to be disabled independently of clock for bus sharing or power gating. |
| ZZ | Asynchronous sleep mode input (active low) | Reduces standby current to ≤40 mA while preserving data; no clock required for entry/exit. |
| BWA–BWD | Byte write enable inputs (active low) | Select 1–4 byte lanes for partial writes; avoids full-word overwrites and reduces bus traffic. |
| DQA–DQD, DQPA–DQPD | Data I/O and parity I/O pins | 18-bit data + 4-bit parity (22 total); supports error detection in mission-critical telecom buffers. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous self-timed writes | Eliminates external write pulse timing constraints; internal timing engine ensures reliable write completion across voltage/temperature. |
| IEEE 1149.1 JTAG boundary scan | Enables PCB-level interconnect testing without physical probe access; supported on 119-ball BGA and 165-ball FBGA variants. |
| User-selectable burst mode | Hardware MODE pin configures interleaved or linear addressing - matches host processor expectations without firmware rework. |
| Separate VDD/VDDQ supplies | Permits independent core and I/O voltage domains - essential for mixed-signal SoC interfaces and power domain isolation. |
| Single-cycle chip deselect | Allows rapid switching between multiple SRAMs on shared buses, minimizing dead cycles during bank switching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed pipelined SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV102418BLL-166TQLI | 1024K × 18 organization, 3.3 V only I/O (no 2.5 V support), no JTAG, 165-ball FBGA only | Lacks VDDQ flexibility and boundary scan; requires redesign of PCB layout and test strategy | Choose when board space permits larger FBGA and system uses only 3.3 V I/O. |
| MT28EW128ABA1HPC-0SIT | 128 Mbit Quad SPI NOR flash with Xccela interface; asynchronous, non-volatile, no pipelining | Not functionally equivalent: used for code storage, not high-speed buffering; cannot replace SRAM in latency-critical paths | Not a drop-in replacement; consider only for non-real-time configuration storage, not packet buffering. |
Compared with IS61WV102418BLL-166TQLI and MT28EW128ABA1HPC-0SIT, the CY7C1362C-166AJXC uniquely delivers 18-bit synchronous pipelining with dual-voltage I/O and JTAG in TQFP-100 - critical for upgradeable, testable, and thermally constrained telecom hardware.

FAQ
What is the difference between CY7C1360C and CY7C1362C?
The CY7C1360C is organized as 256K × 36 (9 Mbit), while the CY7C1362C is 512K × 18 (also 9 Mbit). They share identical timing, pinout (in same package variant), and feature set, but differ in data width and depth - making them electrically compatible yet logically distinct for system bus width matching.
Does CY7C1362C-166AJXC support 2.5 V I/O operation?
Yes - VDDQ accepts either 2.5 V or 3.3 V, allowing direct connection to 2.5 V ASICs or FPGAs. The core VDD remains fixed at 3.3 V. This dual-voltage I/O capability is confirmed in the Absolute Maximum Ratings and DC Electrical Characteristics sections of Rev. *U datasheet.
Is JTAG boundary scan available on the TQFP-100 package?
No - JTAG (TCK, TMS, TDI, TDO) is only implemented on the 119-ball BGA and 165-ball FBGA packages. The CY7C1362C-166AJXC (TQFP-100, AJ version) does not include JTAG pins; boundary scan is not supported in this package variant.
Can CY7C1362C operate in asynchronous mode?
No - it is strictly synchronous: all address, data, and control inputs (except OE and ZZ) are registered on CLK's rising edge. There is no asynchronous read/write mode; even single-access cycles require clock synchronization and follow pipelined timing rules.
