Intel 8XC196NT Memory MAP and Circuit for Auto Programming, Slave Programming Mode Memory Map

87C196CB SUPPLEMENT

Table 10-2. Slave Programming Mode Memory Map

Description	Address	Comments
OTPROM	FF2000–FFFFFFH	OTPROM Cells
OFD	0778H	OTPROM Cell
DED†	0758H	UPROM Cell
DEI†	0718H	UPROM Cell
PCCB	0218H	Test EPROM
Programming VCC	0072H	Read Only
Programming VPP	0073H	Read Only
Signature word	0070H	Read Only

†These bits program the UPROM cells. Once these bits are programmed, they cannot be erased, and dynamic failure analysis of the device is impossible.

10.3 MEMORY MAP AND CIRCUIT FOR AUTO PROGRAMMING

Because the 87C196CB has an additional 24 Kbytes of OTPROM, its auto programming memory map (Table 10-3) and circuit (Figure 10-1) differ from those of the 8XC196NT.
