TMP93CS44/S45
Low Voltage/Low Power
CMOS 16-bit Microcontrollers
TMP93CS44F/TMP93CS45F
1. Outline and Device Characteristics
The TMP93CS44/TMP93CS45 are high-speed, advanced 16-bit microcontrollers developed for
controlling medium to large-scale equipment. The TMP93CS45 does not have a ROM, the
TMP93CS44 has a built-in ROM. Otherwise, the devices function in the same way.
The TMP93CS44F/TMP93CS45F are housed in 80-pin flat package (P-LQFP80-1212-0.50E).
The device characteristics are as follows:
(1) Original 16-bit CPU (900/L CPU)
• TLCS-90 instruction mnemonic upward compatible
• 16-Mbyte linear address space
• General-purpose registers and register bank system
• 16-bit multiplication/division and bit transfer/arithmetic instructions
• Micro DMA: 4 channels (1.6 µs per 2 bytes at 20 MHz)
(2) Minimum instruction execution time: 200 ns at 20 MHz
(3) Internal RAM: 2 Kbytes
Internal ROM: TMP93CS44
TMP93CS45
64-Kbyte ROM
None
(4) External memory expansion
• Can be expanded up to 16 Mbytes (for both programs and data)
• AM8/ ΑΜ16 pin (Select the external data bus width)
• Can mix 8- and 16-bit external data buses (Dynamic bus sizing)
(5) 8-bit timer: 4 channels
(6) 16-bit timer: 2 channels

3.1.2
AM8/ AM16 pin
(1) TMP93CS44
Set this pin to “H”. After reset, the CPU accesses the internal ROM with 16-bit bus
width. The bus width when the CPU accesses an external area is set by bus width/wait
control registers and the registers of port 1, which are described in section 3.6.3. (The
value of this pin is ignored and the value set by register is active.)
(2) TMP93CS45
1. With fixed 16-bit data bus external 16-bit data bus or 8-bit data bus is selectable
Set this pm to “L”. Port 1, AD8 to AD15 and A8 to A15 pins are fixed to AD8 to
AD15 functions. The values set in port 1 control register and port 1 function
register are invalid.
The external data bus width is set by the bus width/wait control register which
is described in section 3.6.3.
It is necessary to set the program memory to be accessed to 16-bit data bus after
reset.
2. With fixed external 8-bit data bus
Set this pin to “H”. Port l, AD8 to AD15 and A8 to A15 pins are fixed to A8 to
A15 functions. The values set in port 1 control register and port 1 function register
are invalid.
The values of bit4 <B0BUS>, <B1BUS> and <B2BUS> in the bus width/wait
control register described in section 3.6.3 are invalid. The external 8-bit data bus
is fixed.
