20 MHz MEMS oscillator with ±25 ppm hold across 165°C
The DSC1524MA2A-20M00000: That ±25 ppm window is tight enough to clock a Cortex-M4 UART at 115200 baud without bit-slip, and the 125°C ceiling means it survives under-hood engine-bay ambient or a reflow oven's cool-down cycle.
Supply and output: 1.8V rail, LVCMOS drive
Runs from a single 1.8V supply rail, drawing a maximum of 7.5 mA—low enough for a battery-powered sensor node's always-on clock tree.
4-VFLGA footprint and assembly note
Housed in a 4-VFLGA package measuring 2.00 mm x 1.60 mm with a seated height of 0.89 mm—a tiny land-grid array that demands a well-tuned solder-paste stencil and a reflow profile matching the JEDEC J-STD-020 moisture sensitivity level.
Listed as Active by Microchip, so this part is still a valid design-in choice for new production builds—no last-time-buy deadline to manage.
