Memory IC

Puya non-volatile memory, organised exactly like the official Puya portfolio: NOR Flash by operating voltage, EEPROM by grade. 165 part numbers listed.

NOR Flash · 108 parts

SPI NOR Flash — by operating voltage

Classified the same way as the Puya official portfolio: H / L / U / N voltage families, with automotive grade (AEC-Q100) listed separately.

H Series · 2.3 V – 3.6 V · 32 parts — Mainstream 3 V family, 1 Mbit – 128 MbitL Series · 1.65 V – 2.0 V · 48 parts — Low power 1.8 V family, 1 Mbit – 1 GbitU Series · 1.65 V – 3.6 V · 14 parts — Wide voltage, one part for 1.8 V and 3.3 VN Series · 1.05 V – 2.0 V · 6 parts — Ultra-low voltage for 1.2 V platformsAutomotive · 2.7 V – 3.6 V · 8 parts — AEC-Q100, −40 to +125 °C, 4 Mbit – 512 Mbit
