Product details
Overview
CY7C10212CV33-12BAXET from Infineon (acquired Cypress Semiconductor) is a 1024 Kb asynchronous CMOS static RAM with 64K × 16 organization, 12 ns access time, and automotive-grade (-40°C to +125°C) operation at 3.0–3.6 V supply. It serves as main memory or buffer in engine control units, ADAS domain controllers, and infotainment head units requiring deterministic timing and AEC-Q100 compliance.
For engineers reviewing the CY7C10212CV33-12BAXET datasheet, CY7C10212CV33-12BAXET pinout, CY7C10212CV33-12BAXET application, or CY7C10212CV33-12BAXET equivalent, key selection criteria include 12 ns speed grade, FBGA-48 package compatibility with high-density PCB layouts, automotive temperature range validation, and VCC/VCCQ dual-supply support for mixed-signal interfacing.
Technical Context
This SRAM implements full asynchronous read/write control with independent byte-enable (UB/LB) signals, enabling 8-bit sub-word access within the 16-bit data bus. Its architecture supports no-wait-state operation across the full automotive temperature range without refresh cycles or clock management overhead.
The device uses a 7×7 mm FBGA-48 package with Sn/Ag/Cu solder balls and MSL Level 3 moisture sensitivity, requiring reflow per Cypress's 260°C peak profile. VCC and VCCQ are separately buffered to isolate core logic from I/O drivers, supporting clean signal integrity in noisy automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61WV102416BLL-12MLI | 12 ns speed, same 64K × 16 density, but commercial temp range (-40°C to +85°C) only | Not qualified for under-hood deployment; lacks AEC-Q100 documentation | Select only for non-automotive industrial control where extended temperature is not required |
| AS6C1008-12ZIN | 1024 Kb density but 8-bit organization (128K × 8); 12 ns speed; automotive temp rated | Requires data bus width adaptation; different addressing scheme impacts firmware porting effort | Choose when system uses 8-bit microcontrollers or requires higher word count over narrower bus |
Compared with IS61WV102416BLL-12MLI, CY7C10212CV33-12BAXET delivers guaranteed operation up to +125°C and full AEC-Q100 test reports; versus AS6C1008-12ZIN, it offers native 16-bit data width-reducing address decoding complexity and PCB layer count in 16-bit MCU designs.

FAQ
What is the maximum clock frequency supported by CY7C10212CV33-12BAXET?
This is an asynchronous SRAM and does not use a clock signal. Its performance is defined by access time (12 ns) and cycle time (20 ns), not frequency. Timing is controlled solely by CE#, OE#, and WE# assertion/deassertion, making it suitable for microcontrollers without dedicated memory clocks.
Does CY7C10212CV33-12BAXET support battery backup or data retention mode?
No. This device is a standard volatile asynchronous SRAM with no built-in battery-backup circuitry or sleep/standby retention mode. Data is lost when VCC drops below minimum operating voltage. External power-fail detection and backup capacitors must be implemented at system level if retention is required.
Can UB# and LB# be used simultaneously for full 16-bit writes?
Yes. When both UB# and LB# are asserted low, the full 16-bit data bus (IO0–IO15) is enabled for write operations. Holding either high disables the corresponding byte lane, allowing selective 8-bit updates without read-modify-write sequences.
Is the FBGA-48 package lead-free and RoHS compliant?
Yes. The package uses Sn/Ag/Cu (SAC405) solder balls and is fully RoHS compliant, with documented Certificate of Compliance and IPC-1752 material declarations confirming Pb-free status and halogen-free mold compound (KEG2270).
