Microchip lists the DSC6001JI2A-PROGRAMMABLE as Obsolete.
This covers under-hood and cabin environments where a quartz oscillator might drift or fail under vibration; the MEMS resonator handles the shock profile better. The 4-SMD no-lead package (2.50 mm x 2.00 mm) is a standard footprint for MEMS oscillators — rework with hot air is straightforward if the pad layout matches the datasheet land pattern.
Supply voltage and frequency range
Operates from 1.71 V to 3.63 V — a single supply rail covers 1.8 V, 2.5 V, and 3.3 V logic families without a level translator. The programmable frequency range spans 1 MHz to 80 MHz, set by the factory or via a programming tool before assembly. The CMOS output drives standard logic inputs directly.
