AD570 is a universal 44 pin PLCC adapter for the Pin-Master 48. It is designed to allow most 44 pin PLCC devices to be programmed on a Pin-Master 48 without changing adapter. The implementations of the design and tests were made by using dedicated circuit boards to each processor; microcontrollers AT89C51RC (CISC) and ATmega64 (RISC), both made by the manufacturer Atmel.

Take a look at its datasheet. (You did look at the datasheet didn't you?) In the description on the first page it says "15 I/O lines". This means you can have a maximum of 15 LEDs/Buttons/etc. You will need to choose a microcontroller with at least 19 I/O lines (17 LEDs + 1 switch + 1 piezo). How about the AT89C51RC, it's got 32 I/O lines. The AT89C51RC is a low-power, high-performance CMOS 8-bit microcontroller with 32K bytes of Flash programmable read-only memory and 512 bytes of RAM. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 and 80C52 instruction set and pinout.
