With a minimum instruction execution time of 400 ns (10MHz clock), the MSM65512A is capable of high-speed processing, and includes 8K bytes of program memory, 256 bytes of data memory, timers and serial ports. Also available are the MSM65P512A, which replaces the MSM65512's built-in program memory with one-time PROM, and the MSM65X512A, which uses external program memory. www.DataSheet4U.com FEATURES • Operating range Operating frequency Operating voltage Operating temperature • Memory space Internal program memory Internal data memory • Minimum instruction execution time • Powerful instruction set : 0 to 10 MHz (VDD=4.5 to 5.5 V) 0 to 5 MHz (VDD=2.7 to 5.5 V) : 2.7 to 5.5 V : –40 to +85°C (Operation at +125°C is assured by the other specification.) : 64K bytes : 8K bytes : 256 bytes : 400 ns @ 10 MHz : 83 basic instructions 8/16-bit operation instructions Bit manipulation instructions Compound function instructions : 8 ¥ 8 Æ 16 16/8 Æ 16 ... 8 : 4 ports ¥ 8 bits : 8-bit auto-reload timer ¥ 2 16-bit auto-reload timer ¥ 1 Watchdog timer ¥ 1 : Time base counter ¥ 1 16-bit free-running counter ¥ 1 : 1 channel : 2 channels : Shift register ¥ 1 Serial port with baud rate generator (UART/synchronous) ¥ 1 : 3 : 15 • Abundant addressing modes • Multiplication/division operation functions • I/O ports Input-output port • Timers • Counters • Capture input • Compare output • Serial ports • External interrupts • Interrupt sources • Package 40-pin plastic DIP (DIP40-P-600-2.54) : (MSM65512A-¥¥¥RS, MSM65P512A-¥¥¥RS) 44-pin plastic QFP (QFP44-P-910-0.80-2K) : (MSM65512A-¥¥¥GS-2K, MSM65P512A-xxxGS-2K) 44-pin plastic QFJ (PLCC) (QFJ44-P-S650-1.27): (MSM65512A-¥¥¥JS, MSM65P512A-¥¥¥JS) ¥¥¥ indicates the code number. 1/23 www.DataSheet4U.com BLOCK DIAGRAM ¡ Semiconductor OSC 0 OSC 1 RESET HSTOP* ROM (8K bytes) OSC CONT.
