AT27C010(l) 2 the AT27C010(l) in available in a choice of industry stan- dard jedec-approved one-time programmable (otp) plastic pdip, plcc, and tsop packages. all devices fea- ture two line control (ce , oe ) to give designers the flexibil- ity to prevent bus contention. with 128k byte storage capability, the AT27C010(l) allows firmware to be stored reliably and to be accessed by the system without the delays of mass storage media. atmels 27c010(l) have additional features to ensure high quality and efficient production use. the rapid? program- ming algorithm reduces the time required to program the part and guarantees reliable programming. programming time is typically only 100 s/byte. the integrated product identification code electronically identifies the device and manufacturer. this feature is used by industry standard programming equipment to select the proper programming algorithms and voltages. system considerations switching between active and standby conditions via the chip enable pin may produce transient voltage excursions. unless accommodated by the system design, these tran- sients may exceed data sheet limits, resulting in device non-conformance. at a minimum, a 0.1 m f high frequency, low inherent inductance, ceramic capacitor should be uti- lized for each device. this capacitor should be connected between the v cc and ground terminals of the device, as close to the device as possible. additionally, to stabilize the supply voltage level on printed circuit boards with large eprom arrays, a 4.7 m f bulk electrolytic capacitor should be utilized, again connected between the v cc and ground terminals. this capacitor should be positioned as close as possible to the point where the power supply is connected to the array. block diagram

AT27C010(l) 8 rapid programming algorithm a 100 m s pgm pulse width is used to program. the address is set to the first location. v cc is raised to 6.5v and v pp is raised to 13.0v. each address is first programmed with one 100 m s pgm pulse without verification. then a verification / reprogramming loop is executed for each address. in the event a byte fails to pass verification, up to 10 successive 100 m s pulses are applied with a verification after each pulse. if the byte fails to verify after 10 pulses have been applied, the part is considered failed. after the byte verifies properly, the next address is selected until all have been checked. v pp is then lowered to 5.0v and v cc to 5.0v. all bytes are read again and compared with the origi- nal data to determine if the device passes or fails.
