Supply Voltage and Write Protect Voltage
315Y⁽¹⁾ = V_CC = 4.5 to 5.5V; V_PFD = 4.25 to 4.50V
315V = V_CC = 3.0 to 3.6V; V_PFD = 2.80 to 2.97V
315W = V_CC = 2.7 to 3.3V; V_PFD = 2.60 to 2.70V
Speed
–65 = 65ns (315Y)
–85 = 85ns (315V/W)
Package
MH⁽²⁾ = SOH28
MQ = SO16
Temperature Range
6 = –40 to 85°C
Shipping Method
For SOH28:
blank = Tubes (Not for New Design - Use E)
E = Lead-free Package (ECO PACK^®), Tubes
F = Lead-free Package (ECO PACK^®), Tape & Reel
TR = Tape & Reel (Not for New Design - Use F)
For SO16:
blank = Tubes (Not for New Design - Use E)
E = Lead-free Package (ECO PACK^®), Tubes
F = Lead-free Package (ECO PACK^®), Tape & Reel
TR = Tape & Reel (Not for New Design - Use F)
Note: 1. Contact Local Sales Office
2. The SOIC package (SOH28) requires the SNAPHAT^® battery package which is ordered separately under the part number “M4TXX-
BR12SHX” in plastic tube or “M4TXX-BR12SHXTR” in Tape & Reel form (see Table 17).
Caution: Do not place the SNAPHAT battery package “M4TXX-BR12SH” in conductive foam as it will drain the lithium button-cell bat-
tery.
For other options, or for more information on any aspect of this device, please contact the ST Sales Office
