MEMS oscillator with AEC-Q100 qualification
The DSC1001DL5-008.0000T is an 8 MHz MEMS-based oscillator from Microchip's DSC1001 series, rated AEC-Q100 for automotive-grade reliability. That qualification means it has passed the temperature cycling, ESD, and lifetime stress tests required for under-hood and chassis-domain electronics — not just cabin infotainment. Its CMOS output and wide supply range of 1.8V to 3.3V let it clock 1.8V or 3.3V logic directly, without a level translator. The ±10ppm frequency stability keeps serial buses (UART, SPI, I2C) within bit-rate tolerance across temperature.
Temperature grade and deployment envelope
Think engine-bay ECUs, outdoor telecom base stations, or factory-floor PLCs that see 85°C ambient with internal self-heating. The MEMS resonator is inherently more shock- and vibration-tolerant than a quartz crystal — no mechanical fracture risk under 50 g impacts or continuous vibration on a motor drive.
Power budget and standby mode
Max supply current is 6.3 mA during active oscillation — low enough for a battery-powered sensor node that runs on a coin cell. When the system enters sleep, the Standby (Power Down) function drops draw to 15 µA max, preserving battery life during long idle periods.
Package and board layout fit
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm max. The no-lead footprint saves board area and avoids bent-lead issues during pick-and-place. Standard reflow profile applies — no special handling beyond MSL level typical for MEMS oscillators.
This is a current-production part suitable for new designs.
