The MAX9960 dual-flash-pin electronics/supervoltage
switch matrix replaces most of the relays and switches
commonly needed to connect system resources to
each of two pins in a flash memory or SOC ATE system
(Figure 1). The device provides seven switches per
channel to select up to four independent sources: the
pin electronics (PE), two parametric measurement units
(PMUs) or other Kelvin analog resources, and a flash
memory programming supervoltage (FVHH_). The
force-and-sense PMU switches are independently controlled,
enabling their use to connect two non-Kelvin
resources in place of each PMU or Kelvin resource.
Each MAX9960 contains two complete seven-switch
channels with fully independent controls.
The MAX9960 features signal path switches with wide
600MHz bandwidth, low 3 series resistance, and low
8pF shunt capacitance over a voltage range compatible
with common pin electronics ICs. An on-chip voltage-
doubling buffer with selectable 1x or 2x gain
generates the flash supervoltage, allowing a 6.5V DAC
reference input to generate up to a maximum of 13V for
flash-memory programming levels.
When switching from the FVHH_ to PE_ or from PE_ to
FVHH_, the device-under-test (DUT_) voltage behaves
monotonically. Switching transitions between the PE_
and FVHH_ inputs are typically less than 350ns.
The MAX9960 operates over a commercial 0°C to
+70°C temperature range, and is available in the 48-pin
thin QFN package (7mm x 7mm x 0.8mm) with an
exposed pad on the bottom for heat removal.
