PROM VERSION OF M37735MHLXXXHP
TIMING REQUIREMENTS (VCC = 2.7 – 5.5 V, VSS = 0 V, Ta = –40 to +85 °C, f(XIN) = 12 MHz, unless otherwise noted (Note 1))
Notes 1. This applies when the main clock division selection bit = “0” and f(f2) = 6 MHZ.
2. Input signal’s rise/fall time must be 100 ns or less, unless otherwise noted.
