CMOS 16-Bit Microcontroller
TMP93CW44DF
1. Outline and Device Characteristics
The TMP93CW44 are high speed, advanced 16-bit microcontroller developed for controlling
medium to large-scale equipment.
The TMP93CW44DF are housed in 80-pin flat package (P-QFP80-1420-0.80B).
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: 4 Kbytes
Internal ROM: 128 Kbytes
(4) External memory expansion
• Can be expanded up to 16 Mbytes (for both programs and data)
• AM8/ AM16 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
(7) Serial interface: 2 channels
