... HCS101 1.0 SYSTEM OVERVIEW As indicated in the block diagram in Figure 1-1, the HCS101 has a small EEPROM array, which must be loaded with several parameters before use. These parameters include: • Two 32-bit serial numbers • 16-bit counter value • Additional 10-bit serial number • Configuration data ...

... DEVICE OPERATION As shown in the typical application circuits in Figure 2- 1, the HCS101 is easy to use. It requires only the addi- tion of buttons and RF circuitry for use as the transmit- ter in your application. A description of each pin is given in Table 2-1. FIGURE 2-1: TYPICAL CIRCUITS ...

... Serial Number 2 is transmitted when all buttons are pressed DS41115C-page 4 3.2 Code Word Organization The HCS101 transmits a 66-bit code word. The 66-bit word is constructed from the serial numbers, counter and function information. The code word format is shown in Figure 3-2. Under normal conditions, serial number 1 is transmitted with the counter and serial number 3 ...

... HCS101 4.3.4 MINIMUM FOUR TRANSMISSIONS (MTX4) If this bit is cleared, at least one code word is completed when the HCS101 is activated. If this bit is set, at least four complete code words are transmitted. 4.3.5 TRANSMIT PULSE ENABLE (TXEN) If this bit is cleared, no start pulse occurs before a transmission. If the bit is set, a start pulse (1 T transmitted before the first code word’ ...

... PROGRAMMING THE HCS101 When using the HCS101 in a system, the user will have to program some parameters into the device, including the serial number and the counter, before it can be used. The programming cycle allows the user to input a 192-bit serial data stream which is then stored inter- nally in EEPROM ...
