MSM83C154S Features

• Full static circuitry
• Internal program memory (ROM)
16384 words * 8 bits (MSM83C154S)
• External program memory (ROM)
   Connectable up to 64K bytes
• Internal data memory (RAM)
   256 words * 8 bits
• External data memory (RAM)
   Connectable up to 64K bytes
• Four sets of working registers (R0 thru R7 * 4)
• Stack Free use of 256-word * 8-bit internal data memory area
• Four input/output ports (8-bit * 4)
• Serial ports (UART operation)
• Six types of interrupts
   (1) Two external interrupts
   (2) Three timer interrupts
   (3) One serial port interrupt
* Priority allocated interrupt processing
* Multi-level interrupt processing by software management
• CPU power down function
(1) Idle mode: CPU stopped while oscillation continued.
                                                           (Software setting)
(2) PD mode: CPU and oscillation all stopped.
                                                           (Software setting)
                 (Setting I/O ports to floating status possible)
  (3) HPD mode: CPU and oscillation all stopped.
                                                          (Hardware setting)
                 (Setting I/O ports to floating status possible)
• CPU power down mode cancellation
(1) Execution commenced from address 0 by CPU resetting.
                                  (IDLE, PD, and HPD mode cancellation)
* RESET pin is used
(2) Execution from interrupt address by interrupt request, or execution resumed from next address after the stop address. (IDLE and PD mode cancellation)
* External, timer, and serial port interrupts
• I/O control registers (0F8H)
   b0: Port 0, 1, 2, and 3 floating setting (PD, HPD)
   b1: Port 1 high impedance input port setting
   b2: Port 2 high impedance input port setting
   b3: Port 3 high impedance input port setting
   b4: Port 1, 2, and 3 pull-up resistance switching (10 k pull-up resistance switch off to leave only 100 k)
   b5: Serial port reception error detector bit
   b6: 32-bit timer mode setting (TL0+TH0+TL1+TH1)
• Timer/counters (three 16-bit timer/counters)
   (1) 8-bit timer with 5-bit prescalar
   (2) 16-bit timer
   (3) 8-bit timer with 8-bit auto-reloader
   (4) 8-bit separate timer
   (5) 16-bit timer with 16-bit auto-reloader
   (6) 16-bit capture timer
   (7) 16-bit baud rate generator timer
   (8) 32-bit timer
• Wide operating temperature range 40 to +85°C
• Wide operating voltage range
   (1) When operating: V_CC=+2.2 to 6V (varies according to frequency)
   (2) When stopped:V_CC=+2 to +6V (PD or HPD mode)
• Instruction execution cycle
   (1) 2-byte 1-machine cycle instructions
   (2) Multiplication/division instructions
• Direct initialization of ports 0, 1, 2, and 3 by input of reset signal even if oscillator have been stopped.
   (All ports output "1".)
• High noise margin (with Schmitt trigger input for each I/O)
• 40-pin plastic DIP/44-pin plastic flat package/44-pin plastic PLCC/44/pin plastic TQFP
• Software compatibility with MSM80C31F and MSM80C51F
