H Single Chip Bar Code Decode IC Technical Data HBCR-1610 HBCR-1611 HBCR-1612 Features * Supports Five Industry Standard Bar Code Symbologies * Automatic Code Recognition * Choice of Parallel or Full Duplex Serial ASCII Interface * Programmable via Escape Sequences or Pin Strapping * CMOS * Through Hole and Surface Mount Packages * Audio and Visual Feedback Control Description The Hewlett-Packard Single Chip Bar Code Decoder IC offers flexible bar code decoding that is designed to give OEMs the ability to address a growing number of industry segments and applications. Flexibility is made possible through firmware that allows the IC to automatically recognize and decode the most popular bar code symbologies. User implementation is easy since only a few supporting components are required. The HBCR-1610 series decodes the most popular bar code symbologies used in applications in government, retail, industrial and medical markets. The IC 5965-5950E automatically discriminates and decodes the following symbologies: * Code 39 (Standard or Extended) * Interleaved 2 of 5 * UPC A, E0, E1 * EAN/JAN 8, 13 * Codabar * Code 128 All bar codes may be scanned bidirectionally except for UPC/ EAN/JAN bar codes with supplemental digits, which must be scanned so that the supplemental digits are scanned last. Scanner Input The HBCR-1610 decode ICs are designed to accept input from hand held digital scanners and slot readers. The maximum scan speed is 30 ips (73 cm/s). Data Communications The serial port supports a variety of baud rates, parity, and stop bits as described in Table 5. The IC has a "Single Read Mode" which allows the application program to stop data input until a "Next Read" command has been received. This allows the host computer to process data transmissions before enabling subsequent reads. Control of data transmission is available using the standard XON/XOFF (D1/ D3) handshake. The parallel port is accomplished via an external 74HCT646 (octal bus transceiver) or two 74HCT574s (octal latches). There are handshake lines for both data and commands. Feedback Features Both audible and visual feedback are possible with the HBCR-1610 series. In both cases, the feedback outputs from the IC should be buffered before driving the transducer. An LED or beeper connected to the IC is either controlled directly by the IC, with signals generated by successful decodes, or controlled by the host system. The tone of the beeper can be configured to one of 16 tones, or can be silenced. 4-37 Power Requirements The decoder IC is operated from a +5 volt DC power supply. The maximum current draw is 24 mA. The maximum power supply ripple voltage should be less than 100 mV, peak-to-peak. Table 1. Recommended Operating Conditions Idle Mode The IC automatically reduces power consumption whenever there is no scanning or decoding activity, or when there is no activity on the I/O port. See Table 4. Notes: 1. Maximum power supply ripple of 100 mV peak-to-peak. 2. The IC can use either an 11.059 or a 16.000 MHz crystal or ceramic resonator. The FRQ pin selects the frequency that matches the oscillator.

Ordering Information Part Number HBCR-1610 HBCR-1611 HBCR-1612 HBCR-1697 Option A01 Option B01 Description CMOS, 40 pin DIP, bulk shipment, no manual CMOS, 44 pin PLCC, bulk shipment, no manual CMOS, 40 pin QFP, bulk shipment, no manual HBCR-1610 Series Users Manual IC individually bagged, no manual IC individually boxed with manual and data sheet IC Configuration The default configuration is set when the IC powers up or when a Hard Reset command is received. Default configuration of many of the options is dependent on the logic states of IC pins, as shown in Table 5. A complete description of the pins and all possible configurations is in the Users Manual. More complete and flexible configuration is achieved using escape sequence commands. There are two pins that cause significant changes in the IC operation. 4-38 FRQ Pin The FRQ pin is used to tell the IC what frequency oscillator is attached to the IC. Using the higher frequency allows greater maximum scan speeds, but causes the IC to draw slightly more supply current. If the state of the FRQ pin does not match the actual oscillator, beeper tones, LED flash length, parallel port timing, and serial port baud rates are adversely affected. FRQ 0 1 Oscillator Frequency 16.000 MHz 11.059 MHz IOM Pin The IOM pin selects between the serial and parallel I/O mode of the IC. Depending on the state of the IOM pin, definitions of several configuration pins change or move to new positions. IOM 0 1 I/O Mode Parallel Serial Escape Sequences Table 7. Escape Sequences The following set of escape sequences is used to control the IC and change its default configuration. Note that all configuration changes will be lost after a Hard Reset, or after power up. Detailed information on how to formulate and use escape sequences is given in the Users Manual.

SERIAL LEVEL CONVERTER GND HBCR-161X 4-41 Surface Mount IC Drying Whenever Vapor Phase or Infrared Reflow technologies are used to mount either of the surface mount packages, there is a possibility that previously absorbed moisture, heated very rapidly to the reflow temperatures, may cause the package to crack from internal stresses. There is a reliability concern that moisture may then enter the package over a period of time, and metal corrosion may take place, degrading the IC performance. To reduce the amount of absorbed moisture and prevent cracking, all of the surface mount ICs should undergo one of the following baking cycles. The parts MUST then be mounted within 48 hours. If the parts are not mounted within 48 hours, they must be rebaked. The total number of baking cycles must not exceed two (2). If the ICs are baked more than twice, Hewlett-Packard cannot guarantee the performance and reliability of the parts. Neither bake cycle can be performed in the standard shipping tubes. The ICs must be baked in an ESD safe, mechanically stable container, such as an aluminum tube or pan. Cycle A B Temperature 125C 60C Time 24 Hours 96 Hours Note: Cycle B must be done in an atmosphere of <5% relative humidity air or nitrogen.
