Internal RAM:
Memory expansion
External memory:
General-purpose serial interface (1 channel)
Asynchronous mode, I/O interface mode
8-bit timers (4 channel): (2 external clock inputs)
Port with zero-cross detection circuit (4 inputs)
Input/Output ports (56 pins)
128 bytes
60K bytes
With its 8-bit CPU, ROM, RAM, timer/event counter and gen-
eral-purpose serial interface integrated into a single CMOS chip,
the TMP90C400 allows the expansion of external
memories for programs and data (up to 60K bytes). The
TMP90C401 is the same as the TMP90C400 but without
ROM.
The TMP90C400N/401N is in a shrink Dual Inline Package
(SDIP64-P-750).
The TMP90C400F/401F is in a Quad Flat package
(QFP64-P-1420A)

- Allows I/O selection on bit basis
- Multiplexer ports of address data bus
The characteristics of the TMP90C400 include:
(10) Interrupt function: 7 internal interrupts and 3 external
interrupts
(11) Micro Direct Memory Access (DMA) function (8 channels)
(12) Standby function (4 HALT modes)
