The 8XC51SL, based on Intel’s industry-standard MCS
é
51 microcontroller family, is designed for keyboard
control in laptop and notebook PCs. The highly integrated keyboard controller incorporates an 8042-style UPI
host interface with expanded memory, keyboard scan, and power management. The 8XC51SL supports both
serial and scanned keyboard interfaces and is available in pre-programmed versions to reduce time to market.
The Low Voltage 8XC51SL is the 3.3V version optimized for even further power savings. Throughout the
remainder of this document, both devices will generally be referred to as 51SL.
The 8XC51SL is a pin-for-pin compatible replacement for the 8XC51SL-BG. It does, however have some
additional functionality. Those additional functions are as follows:
1. 16K OTP ROM: The 8XC51SL-BG had only 8K of ROM.
2. New Register Set: The 8XC51SL adds a second set of host interface registers available for use in support-
ing power management. This required an additional address line (A1) for decoding. To accommodate this,
one V
CC
pin was removed. However, in order to maintain compatibility with the -BG version, an enable bit
for this new register set was added in configuration register 1. This allows the 8XC51SL to be drop in
compatible to existing 8XC51SL-BG designs; no software modifications required.
NOTE:
The changes made to the V
CC
pins require that all three V
CC
pins be properly connected. Failing to do so
could result in high leakage current and possible damage to the device.
