2. Introduction
This Si50x-FPB1 User’s Guide documents immediately useful information for programming blank devices (DUTs)
and additional reference details in support of the Si50x-FPB1(FPB). This document also describes the operation
of the Silicon Laboratories Si50x-FPB1 field programmer kit. The Si50x-FPB1 kit refers to the field programmer
board hardware and software intended for field programming of the Si501, 502, 503, and 504 CMEMS oscillators.
The term, “field programming” as it is used in this document refers to writing the write-once configuration registers in Non-Volatile
Memory (NVM). The NVM controls the configuration of the device on powerup.
2.1. Kit Contents
The Si50x-FPB1 kit contains the following:
Si50x Field Programmer Board
Plastic tweezers
Metal tweezers
USB Type B retractable cable
2 canisters w/ blanks on tape inside
25 blank 2025 parts

4. Functional Description
Figure 7. Block Diagram
The pages that follow provide the detailed functional description of the hardware. The FPB schematics, bill of
materials, and PCB layouts are included as sections 15, 16, and 17, respectively. Figure 7 provides a block
diagram for the board.
Location descriptions in this document assume the reader is viewing the board in the conventional orientation, i.e.,
looking down on the top side (primary side) with the silkscreen text right side up as in Figure 5.
4.1. Power Supply
The Si50x-FPB1 is pre-configured to accept +5 V from the USB connector at J1. The +5 V is filtered and routed to
the MCU, the DUT VDD voltage regulator, and to each DUT’s status LEDs. The output of the voltage regulator is
under MCU control and yields either 3.3 V or 4.1 V. The higher voltage is used when writing to the DUT’s NVM. The
power supply components are mounted on the back side of the board

4.2. MCU
The Silicon Laboratories MCU, P/N C8051F380 is alsomountedon the backside oftheboardatU2.TheMCU provides
the following functions:
Supports single-wire communication(C1)to the DUT on behalf of the host PC per the Field Programmable
Oscillator Software
Drives 3-state status indicator LEDs (see Table 3)
Supplies 3.3 V to peripheral ICs (the serial number generator and the C1 voltage level shifter)
Controls DUT voltage supply regulator (see Section “4.1. Power Supply” )
Switches in pull-down near end bias resistors (reserved for future use)
Auto-detects the board type. The firmware identifies the board type MCU via port P1.7 (pin 29). The voltage at
this pin is pulled up internally on the Si50x-FPB1. (The pin is pulled down via an external resistor on the Si501/
2/3/4-EVB customer evaluation board.)

5. Device Support
The FPB has four latch-able sockets installed to support four different surface mount package sizes. These are
enclosed in red in Figure 8 below. To the right of each socket is the corresponding device footprint to further guide
the user as to which socket supports which size package. Note that the pin 1 location is marked in silk screen
beside each package footprint. The device must be inserted into the socket in this orientation to work. Also note
that some landing patterns have six pads. This is to support future differential output devices. The Si501/2/3/4 have
four pins and only support single-ended LVCMOS outputs.
Figure 8. Socket Locations
Reference information regarding sockets and package compatibility is listed in Table 2 below. Sockets are listed in
the same relative order as shown in Figure 8.

6. USB
A 4-pin USB Type B receptacle is provided at location J1. The Si50x-FB1 is compatible with USB Specification 2.0.
This connector is mounted on the back of the PC board in the lower left hand corner. The location is noted on the
top side with silkscreen artwork showing an icon of a PC with bidirectional arrows. See Figure 9 below.

7. Status Signals
The five LEDs on the board are listed in Table 3. Four of these are surface mount tri-color Red, Green, Blue (RGB)
LED units that report the programming status for DUTs in their respective sockets. (Note that yellow or amber is
produced by mixing Red + Green light simultaneously). The location of these LEDS is noted in Figure 10.

8. Current Sense Resistor
There is one current sense resistor located on the FPB designated R7 and placed between test points
VDD_DUT_PIN TP15 and VDD_DUT TP16 in the center back side of the board. R7 is pointed out in the photo
below. The default or pre-loaded resistor value is 2 . The voltage drop across this resistor may be used for
calculating a DUT's current draw and power consumption.

9. Outputs
At this time, the Si50x-FPB1 supports only single-ended format outputs on the Si501/2/3/4 CMEMS oscillator. The
three 6-pin sockets will support differential outputs on future oscillator devices. Near-end bias resistors are installed
to support future devices. All outputs are ac-coupled to test points on the right hand side edge of the board (see
Figure 12). These output test points are also included in Table 4.

10. Headers and Test Points
For reference purposes, all headers (JP*) and test points (TP*) are collected in Table 4. There are no headers
intended for routine jumper use in the current version of the FPB. The output test points give ac-coupled access to
a DUT installed in a socket. Generally, these test points are not populated. (The “NI” in the Notes column means
“Not Installed”.)
