• Manufacturer Part Number: ELANSC310
• Description: Single-Chip, 32-Bit, PC/AT Microcontroller
• Manufacturer: AMD [Advanced Micro Devices]

Notes:
1. LS in the Clock Off column stands for Last State.
2. Reset State Local Bus signal loading 920 mV–0 V. For 33-MHz operation, CPUCLK loading = 30 pF.
All inputs that have VCC clamp = 5 V are 5-V safe inputs regardless of their VCCIO.
