ISD-ES2100DEMO Board Description: The ISD2100 board can be used in conjunction with the ISD15100 evaluation kit as daughter card to demonstrate all functionality of ISD2100 or as stand alone unit that can be connected to the user's system using the on board header pins. The board contains an ISD2100, a 3.5mm audio Jack and speaker header pins. Power and Connectors: Power: Power is supplied to the ISD2100DEMO from the on board connectors if the board is used with the ISD15100 evaluation board. When the board is used a stand alone the J8 is used to connect +3V power to the board using external supplies connected via VCC and GND pins. REFERENCE DESIGNATOR Description GND Ground VCC+ External Spply SUPPLY 0V 2.7V to 3.6V SPI Connection J1, J2 The user's microcontroller can communicate to the on-board ISD2100 via J2. An can monitor the signal on J1. Users need at least the four SPI signals plus a common ground. If users intend to implement digital-read or digital-write commands, they need to poll RDY/BSYB pin for data flow control as well.

Chip-erase the on-board ISD15108 chip. This is to prevent the POI macro of the on-board ISD15108 chip from conflicting with the ISD2100 chip on the daughter card. Unplug the ISD-ES15100_USB board and close the VPE15100. 2. Remove the two jumpers J17 SSB (G) and J21 RDY_BSYB (H). In case the 0-ohm resistor R21 (next to the jumper J17 SSB) is on the board, remove it. Users don't need the 0-ohm resistor as it is fully controlled by the jumper J17. 3. Put the daughter card onto J19 (F). 4. Plug in the ISD-ES15100_USB board and launch the VPE2100 V33D Put J1 and J2 next to each other V33D V33D/VCCPWM J1 FEMALE CONNECTOR1 VCC GNDA 1 3 5 7 9 11 13 15 NC13 INTB/GPIO3 MOSI/GPIO0 SCLK/GPIO1 2 4 6 8 10 12 14 16 RDY _BSYB/GPIO4 SSB MISO/GPIO2 NC13 INTB/GPIO3 MOSI/GPIO0 SCLK/GPIO1 V33D R5 100 R6 100 MOSI/GPIO0 1 SW2 2 SCLK/GPIO1 1 SW3 2 MISO/GPIO2 1 SW4 2 INTB/GPIO3 1 SW5 2 RDY_BSYB/GPIO4 1 CON16A R13 2K TP7 SW6 2 GPIO5 R14 2K V33D R15 2K V33D V33D TP8 TP9 R8 2K 2 U1 2K TP10 1 2 3 4 5 GPIO5 MISO SCLK SSB MOSI VSSD R16 0 V33D C4 1 VCCPWM .1UF GND 4.7uF GNDPWM 1 VCC+ SPK+ 2 C5 J4 SPK+ SPK- 1 2 J3 SPK- 2 3 SPK+ 1 CP-3502N-ND HEADER 2_1 Fig1 ISD-ES210DEMO Schematics SPK- R12 0 J8 C2 .1UF 2K 6 7 8 9 10 J7 I2100_QFN20 Foot Print R9 R7 VCC 1 Not On board ( ReV A bug fix) R17 TP6 MISO/GPIO2 SCLK/GPIO1 SSB MOSI/GPIO0 R11 80K R17 2K RDY_BSY B/GPIO4 SSB MISO/GPIO2 1 R4 100 SW1 2 2 4 6 8 10 12 14 16 C1 10 uF C3 .01UF 20 19 18 17 16 R3 100 TP5 1 1 3 5 7 9 11 13 15 VCC NC NC NC NC NC R2 100 VCC_PW M SPK+ VSS_PW M SPKVCC_PW M R1 100 Ohm V33D/VCCPWM J2 MALE CONNECTOR1 CON16A 2 TP2 2 TP1 GPIO5 VCCD NC RDY INTB 15 14 13 12 11 GPIO5 NC13 RDY_BSY B/GPIO4 INTB/GPIO3 R10 0
