It provides a small package outline and low cost to make this device a perfect solution for unidirectional remote control systems. It is also pin compatible with Microchip’s HCS201 Code Hopping Encoder allowing easy upgrading to a more secure remote keyless entry (RKE) system. 2001 Microchip Technology Inc. Preliminary DS41115C-page 1 HCS101 1.0 SYSTEM OVERVIEW The EEPROM data for each transmitter is programmed by the manufacturer at the time of production. 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: • • • • Any type of controller may be used as a receiver, but it is typically a microcontroller with compatible firmware that allows the receiver to operate in conjunction with a transmitter, based on the HCS101. Two 32-bit serial numbers 16-bit counter value Additional 10-bit serial number Configuration data FIGURE 1-1: BASIC OPERATION OF TRANSMITTER ENCODER Transmitted Information Serial Function Number 3 Bits Counter Serial Number 1 Function Bits EEPROM Array Serial Number 3 Counter Serial Number 1 DS41115C-page 2 Preliminary 2001 Microchip Technology Inc. HCS101 2.0 DEVICE OPERATION As shown in the typical application circuits in Figure 21, the HCS101 is easy to use. It requires only the addition of buttons and RF circuitry for use as the transmitter in your application. A description of each pin is given in Table 2-1. FIGURE 2-1: TYPICAL CIRCUITS VDD B0 B1 S0 VDD S1 NC S2 DATA NC VSS The HCS101 will wake-up upon detecting a switch closure and then delay for a debounce delay (TDB) as shown in Figure 2-2. The device will then update the 16-bit counter before it loads the transmit register. The data is then transmitted serially on the DATA pin in Pulse Width Modulation (PWM) format. If additional buttons are pressed during a transmission, the current transmission is terminated. The HCS101 restarts and the new transmission will contain the latest button information. When all buttons are released, the device completes the current code word and then powers down. Released buttons do not terminate and/or restart transmissions.

Preliminary DS41115C-page 3 HCS101 3.0 TRANSMITTED WORD 3.2 3.1 Transmission Format (PWM Mode) 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. The HCS101 transmission is made up of several code words as shown in Figure 3-1. Each code word starts with a preamble and a header, followed by the data. The code word is followed by a guard period before the next code word begins. The same code word is transmitted as long as the button is pressed. Refer to Table 7-3 for transmission timing requirements. FIGURE 3-1: Code Word Organization Under normal conditions, serial number 1 is transmitted with the counter and serial number 3. If all the buttons are pressed, serial number 2 is transmitted in place of the counter and serial number 3.

CNTR (Counter) SER_1, SER_2, SER_3 (Encoder Serial Number) SER_1, and SER_2 are the 32-bit device serial numbers. SER_3 is an additional 10-bit serial number transmitted with every transmission. The most significant 6 bits of the 16-bit SER_3 word are reserved and should be set to zero. 4.3 OSCILLATOR TUNING BITS (OSC0 TO OSC3) These bits are used to tune the nominal frequency of the HCS101 to within ±10% of its nominal value over temperature and voltage. Configuration Word The configuration word is a 16-bit word stored in the EEPROM array that is used by the device to store the status configuration options. Further explanations of each of the bits are described in the following sections. 2001 Microchip Technology Inc.

Table 4-3 shows how the bit is used to select the different baud rates and Section 5.2 provides a detailed explanation of code word blanking. TABLE 4-3: 0 Basic Pulse Element 400µs Code Words Transmitted All 1 200µs 1 out of 2 BRS Preliminary BAUDRATE SELECT DS41115C-page 5 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) S3 SETTING (S3SET) 5.1 Code Word Completion 5.2 This bit determines the value of S3 in the function code during a transmission and the high trip point selected by VLOWS in Section 4.3.2. If this bit is cleared, S3 mirrors S2 during a transmission. If the S3SET bit is set, S3 in the function code is always set, independent of the value of S2. 4.3.7 SPECIAL FEATURES Code word completion is an automatic feature that ensures the entire code word is transmitted, even if the button is released before the transmission is complete. If the button is held down beyond the time for one code word, multiple code words will result. If another button is activated during a transmission, the active transmission will be aborted and a new transmission will begin using the new button information. If this bit is cleared, no start pulse occurs before a transmission. If the bit is set, a start pulse (1 TE long) is transmitted before the first code word’s preamble. 4.3.6 5.0 Blank Alternate Code Word Federal Communications Commission (FCC) Rules, Part 15 specify the limits on fundamental power and harmonics that can be transmitted. Power is calculated on the worst case average power transmitted in a 100 ms window. It is therefore advantageous to minimize the duty cycle of the transmission by minimizing the duty cycle of the individual bits and by blanking out consecutive words. The transmission duty cycle can be lowered by setting BRS. This reduces the average power transmitted and hence, assists in FCC approval of a transmitter device. Shortening the code word length and transmitting only every other code word (Figure 5-1) also may allow a higher amplitude transmission for greater range. EXTENDED SERIAL NUMBER (XSER) If this bit is cleared, the most significant four bits of the 32-bit Serial Number 1 are replaced with the function code. If this bit is set, the full 32-bit Serial Number 1 is transmitted. 5.3 Auto-Shutoff The auto-shutoff function automatically stops the device from transmitting if a button inadvertently gets pressed for longer than the time-out period, T TO. This will prevent the device from draining the battery if a button gets pressed while the transmitter is in a pocket or purse. 5.4 VLOW: Voltage LOW Indicator The VLOW bit is included in every transmission and will be transmitted as a one if the operating voltage has dropped below the low voltage trip point. Refer to Figure 3-2. The trip point is selectable based on the battery voltage being used. See Section 4.3.2 for a description of how the low voltage select option is set.

HCS101 6.0 PROGRAMMING THE HCS101 The HCS101 will signal that the write is complete by sending out a train of ACK pulses, TACKH high, TACKL low on DATA. The ACK pulses will continue until S2 is dropped. These times can be used to calculate the oscillator calibration value. The first pulse’s width should NOT be used for calibration. 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 internally in EEPROM. Programming will be initiated by forcing the DATA line high after the S2 line has been held high for the appropriate length of time. Refer to Table 6-1 and Figure 6-1. At the end of the programming cycle, the device can be verified as shown in Figure 6-2 by reading back the EEPROM. Reading is done by clocking the S2 line and reading the data bits on the DATA pin. A verify operation can only be done once, immediately following the program cycle. After the Program mode is entered, a delay must be provided to the device for the automatic bulk write cycle to complete. This will write all locations in the EEPROM to all zeros. The device can then be programmed by clocking in 16 bits at a time, using S2 as the clock line and DATA as the data in line. After each 16-bit word is loaded, a programming delay is required for the internal program cycle to complete. This delay can take up to Twc. To ensure that the device does not accidentally enter Programming mode, DATA should never be pulled high by the circuit connected to it. Special care should be taken when driving PNP RF transistors.

Microchip believes that its family of PICmicro microcontrollers is one of the most secure products of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the PICmicro microcontroller in a manner outside the operating specifications contained in the data sheet. The person doing so may be engaged in theft of intellectual property. Microchip is willing to work with the customer who is concerned about the integrity of their code. Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable”. Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our product.
