Product details
Overview
CY7C1361C-100BZXE from Infineon Technologies (formerly Cypress) is a 9-Mbit synchronous flow-through SRAM configured as 256K × 36, operating at 100 MHz with 8.5 ns maximum access time, 3.3 V core supply (VDD), 2.5/3.3 V I/O supply (VDDQ), and IEEE 1149.1 JTAG boundary scan support - used in high-speed cache subsystems for Pentium-class processors.
For engineers reviewing the CY7C1361C-100BZXE datasheet, CY7C1361C-100BZXE pinout, CY7C1361C-100BZXE application, or CY7C1361C-100BZXE equivalent, key selection criteria include burst mode compatibility (interleaved/linear), dual VDDQ support, synchronous self-timed write timing, and TQFP-100 Pb-free packaging with 3-chip-enable architecture.
Technical Context
The CY7C1361C-100BZXE implements a synchronous flow-through architecture where all address, data, and control inputs (ADSP, ADSC, ADV, CE1–CE3, BWx, BWE, GW) are registered on the rising edge of CLK. Burst addressing is managed by a 2-bit on-chip counter that auto-increments after the initial address capture.
It supports two burst sequence types selected via the MODE pin: interleaved (MODE = HIGH) or linear (MODE = LOW); output enable (OE) is asynchronous while sleep mode (ZZ) is controlled independently. All I/Os comply with JEDEC JESD8-5 voltage levels for 2.5 V or 3.3 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 9 Mbit (256K × 36 organization) |
| Max Clock Frequency | 100 MHz - defines maximum sustained burst throughput without wait states |
| Access Time | 8.5 ns - clock-to-output delay under 100 MHz conditions, critical for cache timing closure |
| VDD Supply Range | 3.3 V ±5% - core power tolerance enabling stable operation across industrial temperature range |
| VDDQ Supply Options | 2.5 V or 3.3 V - allows direct interface to mixed-voltage processor buses without level shifters |
| Burst Control | Intel Pentium-compatible interleaved/linear sequences - ensures drop-in compatibility with legacy x86 cache controllers |
| JTAG Support | IEEE 1149.1 compliant - enables board-level testability and in-system debugging of memory subsystems |
Pinout & Package
Package: Pb-free 100-pin TQFP (14 × 20 × 1.4 mm), 3-chip-enable variant (A version), with exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Positive-edge-triggered system clock input | Synchronizes all register-based inputs (addresses, CE, BW, ADV, ADSP/ADSC) and initiates burst cycles |
| ADSP / ADSC | Address strobe inputs (processor/cache controller) | Trigger burst initiation; ADSP used for CPU-initiated bursts, ADSC for controller-initiated bursts |
| ADV | Address advancement control | Controls internal address increment during burst - HIGH advances, LOW holds current address |
| MODE | Burst sequence selection | HIGH = Intel Pentium interleaved burst; LOW = linear burst - determines address mapping for cache line fills |
| CE1, CE2, CE3 | Chip enable inputs (3-enable configuration) | Enable hierarchical depth expansion; CE1 primary, CE2/CE3 for bank selection in multi-SRAM systems |
| ZZ | Deep power-down control | Asynchronous entry into low-current sleep mode (<60 µA standby), independent of clock or bus activity |
| DQA–DQD, DQPA–DQPD | Data I/O groups (36-bit wide) | Four 9-bit byte lanes with individual byte-write enables (BWA–BWD) - enables partial-word writes without read-modify-write |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous self-timed write | Eliminates external write pulse generation - internal timing control ensures reliable data capture across voltage/temperature |
| User-selectable burst mode | Hardware-mode pin (MODE) enables runtime selection between interleaved and linear addressing - matches host CPU requirements |
| Separate ADSP/ADSC strobes | Enables concurrent CPU and cache controller access arbitration - reduces bus contention in multi-master systems |
| JEDEC JESD8-5 I/O compliance | Guarantees interoperability with 2.5 V and 3.3 V logic families without external level translation circuitry |
| Byte-wide write enable (BWA–BWD) | Permits independent write masking of four 9-bit data segments - essential for efficient cache line updates and ECC handling |
Applications
| High-Performance CPU Cache | Network Packet Buffer |
|---|---|
Use Scenario: L2 cache buffer between Pentium-class microprocessor and main memory in embedded computing platforms. IC Role / Device Role / Timing Role: Flow-through SRAM providing zero-wait-state burst reads/writes synchronized to CPU clock domain. Use Value: 8.5 ns access time and 2-1-1-1 burst rate meet tight timing budgets for 100 MHz front-side bus operation. | Use Scenario: Temporary storage for variable-length Ethernet frames in Layer 2 switching ASICs. IC Role / Device Role / Timing Role: High-bandwidth, low-latency packet buffering with byte-selectable writes for header modification. Use Value: 36-bit bus width and per-byte write enables allow efficient 40-byte header edits without full-frame rewrite overhead. |
| Industrial Motion Controller | Radar Signal Preprocessing |
Use Scenario: Real-time trajectory lookup table storage in servo drive firmware executing at 100 MHz. IC Role / Device Role / Timing Role: Deterministic-access memory for position/velocity interpolation tables accessed via burst reads. Use Value: Synchronous flow-through architecture guarantees fixed 8.5 ns latency - critical for jitter-sensitive motion profiling. | Use Scenario: Coherent integration buffer for FMCW radar baseband processing in automotive ADAS modules. IC Role / Device Role / Timing Role: High-speed data staging between ADC interface and FFT engine, supporting 100 MHz sample clock alignment. Use Value: Dual VDDQ support (2.5 V) interfaces directly with low-voltage ADC/DAC chains while maintaining 3.3 V core stability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous burst SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV25636A-100TQLI | 256K × 36, 100 MHz, 3.3 V only (no VDDQ flexibility), no JTAG, no ZZ sleep mode | Lacks deep-sleep and boundary-scan - unsuitable for test-critical or ultra-low-power idle states | Select when JTAG testability and sub-100 µA standby are not required; lower cost alternative for basic caching |
| CY7C1371C-100BZI | Same 256K × 36, 100 MHz, but with pipelined (not flow-through) architecture and 9 ns access | Pipelined latency model introduces 1-cycle read latency - incompatible with zero-wait-state CPU interfaces | Choose only if system design accommodates pipeline staging; not a functional replacement for flow-through timing |
Compared with IS61LV25636A-100TQLI and CY7C1371C-100BZI, the CY7C1361C-100BZXE uniquely delivers flow-through zero-latency burst reads, dual-voltage I/O, JTAG testability, and deep-sleep mode - making it irreplaceable in deterministic real-time cache and packet-processing roles.

FAQ
What is the difference between CY7C1361C and CY7C1363C?
The CY7C1361C is a 256K × 36 (9-Mbit) device, while the CY7C1363C is a 512K × 18 (9-Mbit) variant with identical timing, voltage, and feature set. They share pin compatibility in TQFP packages but differ in address/data width allocation - the former supports wider data paths, the latter higher depth with narrower bus.
Does CY7C1361C-100BZXE support both 2.5 V and 3.3 V I/O simultaneously?
No - VDDQ must be externally set to either 2.5 V or 3.3 V for all I/O banks; it cannot operate with mixed voltages on the same device. The selection is made at power-up and affects all DQ, DQP, and control pins except CLK, ZZ, and MODE.
Can the MODE pin be changed dynamically during operation?
Yes - the MODE pin is sampled on every rising edge of CLK when ADSP or ADSC is asserted to initiate a burst. This allows runtime switching between interleaved and linear burst sequences without reset or reconfiguration.
Is JTAG functionality enabled by default on CY7C1361C-100BZXE?
Yes - IEEE 1149.1 boundary scan is fully implemented and active upon power-up. It requires no configuration; TAP signals (TCK, TMS, TDI, TDO) are dedicated pins in all package variants including the 100-pin TQFP (BZXE).
