PROGRAMMING THE NONVOLATILE MEMORY

The 87C196Kx devices contain from 12 Kbytes to 48 Kbytes of one-time-programmable read-

only memory (OTPROM). Table 16-1 lists the devices and OTPROM sizes. OTPROM is similar

to EPROM, but it comes in an unwindowed package and cannot be erased. You can either pro-

gram the OTPROM yourself or have the factory program it as a quick-turn ROM product (this

option may not be available for all devices). This chapter provides procedures and guidelines to

help you program the device. The information is organized as follows.

security features (page 16-3)

programming pulse width (page 16-8)

modified quick-pulse algorithm (page 16-10)

programming mode pins (page 16-11)

slave programming (page 16-15)

auto programming (page 16-26)

serial port programming (page 16-32)

run-time programming (page 16-44)

Some devices may also be available in windowed EPROM packages. In this

manual, OTPROM refers to the device's internal read-only memory, whether it

is EPROM or OTPROM, and EPROM refers specifically to EPROM devices.
