22 / 25 page ![]() Part numbering STM6519 22/25 Doc ID 022111 Rev 6 11 Part numbering Table 7. Ordering information scheme Example: STM6519 A H A R UB 6 F Device type STM6519 Reset (VCC monitoring threshold) voltage VRST A = no VCC monitoring feature Smart Reset setup delay (tSRC) (1) 1. Smart Reset delay (tSRC) is available from 0.5 s to 10 s in 0.5 s steps (typ.). Minimum order quantities may apply. Contact local sales office for availability. C = factory programmable tSRC = 1.5 s (typ.) H = factory programmable tSRC = 4.0 s (typ.) L = factory programmable tSRC = 6.0 s (typ.) P = factory programmable tSRC = 7.5 s (typ.) U = factory programmable tSRC = 10.0 s (typ.) Inputs, outputs type(2) 2. Push-pull reset output type also available (active-low or active-high). SR input and open drain reset output available with optional pull-up resistor. Minimum order quantities may apply. Contact local sales office for availability. A = active-low SR input with no pull-up, active-low open drain RST output with no pull-up B = active-low SR input with pull-up, active-low open drain RST output with no pull-up Reset timeout period (tREC) A = factory programmable tREC = 210 ms (typ.) B = factory programmable tREC = 360 ms (typ.) E = factory programmable tREC = 1.28 ms (typ.) F = factory programmable tREC = 100 ms (typ.) R = push-button controlled (no defined tREC) Package UC = UDFN-4L UB = UDFN-6L Temperature range 6 = -40 °C to +85 °C Shipping method F = tape and reel |
