Advanced Micro Devices 8237A-BQA is a MOS technology DMA controller from the 8237 series. This component features 4 independent DMA channels, supporting an 8-bit address bus and an 8-bit external data bus. It operates at a maximum clock frequency of 3.125 MHz. The 8237A-BQA is housed in a 40-pin CDIP package with through-hole mounting. Its operating temperature range is -55°C to +125°C, with a nominal supply voltage of 5.0V (4.75V to 5.25V). This device is suitable for applications requiring efficient data transfer in systems such as personal computers and embedded control systems. The package is ceramic, metal-sealed cofired, with a terminal pitch of 2.54mm. Screening level reference standards include 38535Q/M, 38534H, and 883B.
