Microchip Technology TA010-SSYCZB-VAO

The exact TA010-SSYCZB-VAO ordering code selects an automotive-temperature SOIC-8 part using Microchip's pulse-width-modulated single-wire interface (SWI). It is intended for cost-sensitive hardware authentication, such as verifying an EV battery module or an authorized component. The host and device must be provisioned and integrated to the chosen identity or challenge-response policy; the chip does not establish application security by itself.

The database registers 8-SOIC (0.154", 3.90mm Width). Microchip's SS suffix denotes an 8-lead narrow-body SOIC; use the manufacturer's current mechanical drawing to confirm body dimensions, pin-1 marking and PCB land pattern. The local JPG is a generic package illustration, not a photograph of the actual device.

Layout checks

• Confirm pin-1 index and current Microchip footprint.
• Provide VCC decoupling and SWI pull-up circuitry as required.
• Do not copy I2C wiring from the DA-suffix variant.

For the manufacturer's 8-lead SOIC single-wire variant, pins 1-3 and 7 are NC, pin 4 is GND, pin 5 is SI/O, pin 6 is NC and pin 8 is VCC. Pin 5 carries the single-wire serial signal. Confirm the selected powered or parasitic-power connection in the current data sheet.

Operating and current figures depend on interface mode, VCC, temperature and measurement conditions; consult the full electrical tables.

TA010-SSYDAT-VAO uses I2C and a different pin-6 function; it is not a direct host-interface replacement for this CZ single-wire version. Compare provisioned keys, certificates, host code, electrical mode and package before any substitution. No unverified internal product link is included.

Microchip's TA010 CryptoAutomotive Summary Data Sheet DS40002440C explicitly lists TA010-SSYCZB-VAO as an 8-lead SOIC, automotive-temperature, single-wire, bulk tube ordering code. It also documents security resources, SWI pin functions, electrical characteristics and mechanical drawings. Use the latest Microchip revision for design release.

Verify the full SSYCZB suffix, package marking, lot traceability and configured key or certificate records. The generic package image cannot authenticate a physical device. Test real challenge-response behavior with the intended host and trust anchor.

Review the latest Microchip data sheet, errata and package drawing before design release. Validate SWI timing, supply and signal levels, powered versus parasitic mode, credential lifecycle and the complete system threat model.
