Intel® 80C186EA/80C188EA AND 80L186EA/80L188EA 16-Bit High-Integration Embedded Processors Datasheet is a 16-bit high integration embedded microprocessor from Intel, which features static operation, true CMOS inputs and outputs, low power consumption and easy expansion
The Intel 80C186EA/80C188EA and 80L186EA/80L188EA family are 16‑bit high‑integration embedded microprocessors offering static operation, low‑power modes and a rich set of on‑chip peripherals. The datasheet details the core architecture, peripheral blocks, pinout compatibility, operating modes, and electrical specifications for both 3 V and 5 V versions.
Key features include two independent DMA channels, three programmable 16‑bit timers, a local bus controller, and support for the Intel 80C187 numeric coprocessor. Package options are provided for a 68‑pin PLCC, and thermal and AC specifications are listed for design verification.
| Maximum clock speed (3 V version) | 13 MHz |
|---|---|
| Maximum clock speed (5 V version) | 25 MHz |
| DMA channels | 2 Independent DMA Channels |
| Timers | 3 Programmable 16‑Bit Timers |
The processor includes two independent DMA channels for CPU‑independent data transfers.
The 5 V version can operate up to 25 MHz.
