2- / 4-bit Microprocessors


4040

Manufacturer Intel Corp.
Category 4-bit processor
Introduction 1972
Max. Clock
Frequency

0.108 MHz
History

Intel's lowest cost microcomputer during 1975. Gives user the design and computational capability of larger and more complex computers with just a small assortment of easy to use components.

Technology

The 4040 is a complete 4-bit parallel MOS central processing unit. It is an enhanced version of the 4004 and as such retains all the functional capability of that device. It executes all the 4004 instructions, and is also electrically compatible with all components used with a 4004 CPU. The 4040 has 14 additional instructions (60 total) including
- halt or stop

- logical operations
- interrupt enable / disable functions
- ROM-bank switching
- index-register-bank switching

History

During the manufacturing of 4040 the semiconductor industry was interspersed with companies which were not able to deliver the products on time. To show that Intel would meet these market requirements at any time the company created the slogan "Intel Delivers" (see upper side of the 4040 kit, blue Intel logo). Intel met this target in announcing new chip series not until the chips were in stock. Later the slogan changed into "Intel Inside".

Technology

Set can have up to 8K x 8 of program memory in ROM or PROM, 1280 x 4-bit of RAM data memory and over 128 I/O lines, without requiring an interface logic. All components are fabricated with silicon gate, low threshold, PMOS technology.

Technology

The Universal PROM Programmer (UPP) is an Intellec System peripheral capable of programming and verifying the following Intel Programmable ROMs (PROMs): 1702A, 2704, 2708, 2716, 3601, 3602, 3602A, 3621, 3622, 3622A, 3604, 3604A, 3604AL, 3604L-6, 3608, 3624, 3624A, 3625, 3628, 8702A, 8704 and 8708. In addition, the UPP programs the PROM memory portions of the 8748 Microcomputer and the 8755 PROM and I/O chip. Programming and verification operations are initiated from the Intellec Development System console and are controlled by the Universal PROM Mapper (UPM) program.
The basic UPP consists of a controller module, two personality card sockets, front panel, power supplies, chassis and an Intellec Development System interconnection cable. An Intel 4040-based intelligent controller monitors the commands from the Intellec System and controls the data transfer interface between the selected PROM personality card and the Intelec memory. The personality card contains the appropriate pulse generations functions for each Intel PROM family. Programming and verifying any Intel PROM may be accomplished by selecting and plugging in the appropriate personality card. The front panel contains a power-on switch and indicator, reset switch, and two zero-force insertion sockets (one 16-pin and one 24-pin or two 24-pin). A central power supply provides power for system logic and for PROM programming pulse generation.
