TMP93CS40/TMP93CS41
Low Voltage/Low Power CMOS 16-Bit Microcontrollers
TMP93CS40F/TMP93CS41F
TMP93CS40DF/TMP93CS41DF
1. Outline and Device Characteristics
The TMP93CS40/S41 are high-speed advanced 16-bit microcontrollers developed for controlling
medium to large-scale equipment. The TMP93CS41 does not have a ROM; the TMP93CS40 has a
built-in ROM. Otherwise, the devices function in the same way.
The TMP93CS40/S41F are housed in a 100-pin flat package.
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, register bank system
• 16-bit multiplication/division and bit transfer/arithmetic instructions
• Micro DMA: 4 channels (1.6 µs/2 bytes at 20 MHz)
(2) Minimum instruction execution time: 200 ns at 20 MHz
(3) Internal RAM: 2 Kbytes
Internal ROM:

TMP93CS41
64-Kbyte ROM
None
(4) External memory expansion
• Can be expanded up to 16 Mbytes (for both programs and data).
• AM8/ ΑΜ16 pin (selects the external data bus width)
• Can mix 8-/16-bit external data buses.
..... Dynamic bus sizing
(5) 8-bit timer: 2 channels
