12,000 μW/cm
An exposure of 1 hour is recommended with most of standard erasers.
Erasure of the EPROM begins to occur when the chip is exposed to light with wave-
length shorter than approximately 4,000 Å. Since sunlight and fluorescent lighting have
wavelengths in this range, exposure to these light sources over an extended time (about
1 week in sunlight, or 3 years in room-level fluorescent lighting) could cause inadvertent
erasure. If an application subjects the device to this type of exposure, it is suggested
that an opaque label be placed over the window.
The TS80/87C52X2 has four signature bytes in location 30h, 31h, 60h and 61h. To read
these bytes follow the procedure for EPROM verify but activate the control lines pro-
vided in Table 31. for Read Signature Bytes. Table 35. shows the content of the
signature byte for the TS80/87C52X2.
