... Description The E7804 is a quad channel, monolithic ATE pin electronics solution manufactured in a high-performance BiCMOS process. The E7804 operates up to 33 MHz with signals, and 00 MHz with 5V signals. Each channel has a three-statable driver capable of generating 5.4V swings over a –0.2V, +5.2V range. Drivers have independent high and low input levels that are buffered internally. Drivers feature a self-calibrating source impedance, programmable in the range 48Ω ...

... Anode terminal of the on-chip thermal diode string. The pin is ESD protected to VXX, so when measuring the forward drop of the diode string, VXX should be either floating or ≥2V. Cathode of diode string is connected to DGND. No connect pin. No connection is made internally. These pins can be connected to a ground plane to assist in heat removal from the package. 3 E7804 www.semtech.com ...

... E7804s. This topology uses a minimum amount of from the control logic. However, in order to read or write the E7804’s an instruction string bits long needs to be created, clocked all the way through the devices, and a parallel LOAD signal asserted for all devices. NO_OP instructions may be used for the devices that are not being addressed ...

... ASIC a. Minimum # of Control Lines from ASIC Figure 5 depicts the conclusion of a Read instruction being written to the E7804. The first LOAD pulse straddling the rising edge of CLKIN latches in the Read instruction, echoing at SDOUT stops, and the readback of the register begins. After 24 low-going clocks, the data at SDOUT resumes echoing the written data at SDIN ...

... Channel Functions The Channel Functions group of instructions address the functionality of individual registers and bits that are particular to specific channels of the E7804. Driver states, channel switches, calibration factors and set assignments are included in this group. Function Address – These bits denote which function of the particular channels is being addressed. Read Bit– ...

... D0 – writing a one to this bit will close the S7 switch. The S7 switch is a dual pole switch that connects the EPMUS and the EPMUF signals to the PMU_OUT pin. The primary use is when PMU_OUT is externally shorted to the temperature diode ANODE pin. Closing this switch will allow the external PMU to connect to the temperature diode string on an individual E7804 to perform die temperature measurements. ...
